    + Prevent unauthorized code execution during pg_dump (Masahiko Sawada)

      An attacker able to create and drop non-temporary objects could inject
      SQL code that would be executed by a concurrent pg_dump session with the
      privileges of the role running pg_dump (which is often a superuser).
      The attack involves replacing a sequence or similar object with a view
      or foreign table that will execute malicious code.  To prevent this,
      introduce a new server parameter restrict_nonsystem_relation_kind that
      can disable expansion of non-builtin views as well as access to foreign
      tables, and teach pg_dump to set it when available.  Note that the
      attack is prevented only if both pg_dump and the server it is dumping
      from are new enough to have this fix.

    * Tighten security restrictions within REFRESH MATERIALIZED VIEW
      CONCURRENTLY (Heikki Linnakangas)

      One step of a concurrent refresh command was run under weak security
      restrictions.  If a materialized view's owner could persuade a superuser
      or other high-privileged user to perform a concurrent refresh on that
      view, the view's owner could control code executed with the privileges
      of the user running REFRESH. Fix things so that all user-determined code
      is run as the view's owner, as expected.

    * Fix handling of unknown-type arguments in DISTINCT "any" aggregate

      in disclosure of server memory following the text value.

    * Detect integer overflow while computing new array dimensions
      (Tom Lane)

      When assigning new elements to array subscripts that are outside the

      cases.  Memory stomps that are potentially exploitable for arbitrary
      code execution are possible, and so is disclosure of server memory.

    * Prevent the pg_signal_backend role from signalling background workers
      and autovacuum processes (Noah Misch, Jelte Fennema-Nio)

      The documentation says that pg_signal_backend
      cannot issue signals to superuser-owned processes.  It was able to
      signal these background processes, though, because they advertise a
      role OID of zero.  Treat that as indicating superuser ownership.
      The security implications of cancelling one of these process types
      are fairly small so far as the core code goes (we'll just start
      another one), but extensions might add background workers that are
      more vulnerable.

      Also ensure that the is_superuser parameter is set correctly in such
      processes.  No specific security consequences are known for that
      oversight, but it might be significant for some extensions.

    * Fix misbehavior during recursive page split in GiST index build
      (Heikki Linnakangas)

      Fix a case where the location of a page downlink was incorrectly
      tracked, and introduce some logic to allow recovering from such
      situations rather than silently doing the wrong thing.  This error could
      result in incorrect answers from subsequent index searches. It may be
      advisable to reindex all GiST indexes after installing this update.

    * Prevent de-duplication of btree index entries for interval columns

      There are interval values that are distinguishable but compare equal,
      for example 24:00:00 and 1 day.  This breaks assumptions made by btree
      de-duplication, so interval columns need to be excluded from
      de-duplication.  This oversight can cause incorrect results from
      index-only scans.  Moreover, after updating amcheck will report an error
      for almost all such indexes.  Users should reindex any btree indexes on
      interval columns.

    + Prevent CREATE SCHEMA from defeating changes in search_path
      (Report and fix by Alexander Lakhin, CVE-2023-2454)

      Within a CREATE SCHEMA command, objects in the prevailing search_path,
      as well as those in the newly-created schema, would be visible even
      within a called function or script that attempted to set a secure
      search_path.  This could allow any user having permission to create a
      schema to hijack the privileges of a security definer function or
      extension script.

    + Enforce row-level security policies correctly after inlining a
      set-returning function (Report by Wolfgang Walther, CVE-2023-2455)

      If a set-returning SQL-language function refers to a table having
      row-level security policies, and it can be inlined into a calling query,
      those RLS policies would not get enforced properly in some cases
      involving re-using a cached plan under a different role. This could
      allow a user to see or modify rows that should have been invisible.

    + libpq can leak memory contents after GSSAPI transport encryption
      initiation fails (Jacob Champion)

      A modified server, or an unauthenticated man-in-the-middle, can send a
      not-zero-terminated error message during setup of GSSAPI (Kerberos)
      transport encryption.  libpq will then copy that string, as well as
      following bytes in application memory up to the next zero byte, to its
      error report. Depending on what the calling application does with the
      error report, this could result in disclosure of application memory
      contents.  There is also a small probability of a crash due to reading
      beyond the end of memory.  Fix by properly zero-terminating the server
      message. (CVE-2022-41862)

    + Do not let extension scripts replace objects not already belonging to
      the extension (Tom Lane) (CVE-2022-2625)

      This change prevents extension scripts from doing CREATE OR REPLACE if
      there is an existing object that does not belong to the extension.  It
      also prevents CREATE IF NOT EXISTS in the same situation.  This prevents
      a form of trojan-horse attack in which a hostile database user could
      become the owner of an extension object and then modify it to compromise
      future uses of the object by other users.  As a side benefit, it also
      reduces the risk of accidentally replacing objects one did not mean to.

      sandboxes (Sergey Shinderuk, Noah Misch)

      Autovacuum, CLUSTER, CREATE INDEX, REINDEX, REFRESH MATERIALIZED VIEW,
      and pg_amcheck activated the security restricted operation protection
      mechanism too late, or even not at all in some code paths. A user having
      permission to create non-temporary objects within a database could
      define an object that would execute arbitrary SQL code with superuser
      permissions the next time that autovacuum processed the object, or that
      some superuser ran one of the affected commands against it.

      problem. (CVE-2022-1552)

    * Fix default signature length for gist_ltree_ops indexes
      (Tomas Vondra, Alexander Korotkov)

      The default signature length (hash size) for GiST indexes on ltree
      columns was accidentally changed while upgrading that operator class to
      support operator class parameters. If any operations had been done on
      such an index without first upgrading the ltree extension to version
      1.2, they were done assuming that the signature length was 28 bytes
      rather than the intended 8.  This means it is very likely that such
      indexes are now corrupt.  For safety we recommend re-indexing all GiST
      indexes on ltree columns after installing this update.  (Note that GiST
      indexes on ltree[] columns, that is arrays of ltree, are not affected.)

    + Make the server and libpq reject extraneous data after an SSL or GSS
      encryption handshake (Tom Lane)

      A man-in-the-middle with the ability to inject data into the TCP
      connection could stuff some cleartext data into the start of a
      supposedly encryption-protected database session.

      This could be abused to send faked SQL commands to the server, although
      that would only work if the server did not demand any authentication
      data.  (However, a server relying on SSL certificate authentication
      might well not do so.) (CVE-2021-23214)

      This could probably be abused to inject faked responses to the client's
      first few queries, although other details of libpq's behavior make that
      harder than it sounds.  A different line of attack is to exfiltrate the
      client's password, or other sensitive data that might be sent early in
      the session.  That has been shown to be possible with a server
      vulnerable to CVE-2021-23214. (CVE-2021-23222)

    + Prevent integer overflows in array subscripting calculations (Tom Lane)

      The array code previously did not complain about cases where an array's
      lower bound plus length overflows an integer.  This resulted in later
      entries in the array becoming inaccessible (since their subscripts could
      not be written as integers), but more importantly it confused subsequent
      assignment operations.  This could lead to memory overwrites, with
      ensuing crashes or unwanted data modifications. (CVE-2021-32027)

    + Fix mishandling of junk columns in INSERT ... ON CONFLICT ... UPDATE
      target lists (Tom Lane)

      If the UPDATE list contains any multi-column sub-selects (which give
      rise to junk columns in addition to the results proper), the UPDATE path
      would end up storing tuples that include the values of the extra junk
      columns. That's fairly harmless in the short run, but if new columns are
      added to the table then the values would become accessible, possibly
      leading to malfunctions if they don't match the datatypes of the added
      columns.

      In addition, in versions supporting cross-partition updates, a
      cross-partition update triggered by such a case had the reverse problem:
      the junk columns were removed from the target list, typically causing an
      immediate crash due to malfunction of the multi-column sub-select
      mechanism. (CVE-2021-32028)

    + Fix possibly-incorrect computation of UPDATE ... RETURNING outputs for
      joined cross-partition updates (Amit Langote, Etsuro Fujita)

      If an UPDATE for a partitioned table caused a row to be moved to another
      partition with a physically different row type (for example, one with a
      different set of dropped columns), computation of RETURNING results for
      that row could produce errors or wrong answers.  No error is observed
      unless the UPDATE involves other tables being joined to the target
      table. (CVE-2021-32029)

    + Fix failure to check per-column SELECT privileges in some join queries
      (Tom Lane)

      In some cases involving joins, the parser failed to record all the
      columns read by a query in the column-usage bitmaps that are used for
      permissions checking.  Although the executor would still insist on some
      sort of SELECT privilege to run the query, this meant that a user having
      SELECT privilege on only one column of a table could nonetheless read
      all its columns through a suitably crafted query.

      A stored view that is subject to this problem will have incomplete
      column-usage bitmaps, and thus permissions will still not be enforced
      properly on the view after updating.  In installations that depend on
      column-level permissions for security, it is recommended to CREATE OR
      REPLACE all user-defined views to cause them to be re-parsed.

      The PostgreSQL Project thanks Sven Klemm for reporting this problem.

    + Fix information leakage in constraint-violation error messages
      (Heikki Linnakangas)

      If an UPDATE command attempts to move a row to a different partition but
      finds that it violates some constraint on the new partition, and the
      columns in that partition are in different physical positions than in
      the parent table, the error message could reveal the contents of columns
      that the user does not have SELECT privilege on. (CVE-2021-3393)

    + Fix incorrect detection of concurrent page splits while inserting into a
      GiST index (Heikki Linnakangas)

      Concurrent insertions could lead to a corrupt index with entries placed
      in the wrong pages.  It's recommended to reindex any GiST index that's
      been subject to concurrent insertions.

    + Fix CREATE INDEX CONCURRENTLY to wait for concurrent prepared
      transactions (Andrey Borodin)

      At the point where CREATE INDEX CONCURRENTLY waits for all concurrent
      transactions to complete so that it can see rows they inserted, it must
      also wait for all prepared transactions to complete, for the same
      reason.  Its failure to do so meant that rows inserted by prepared
      transactions might be omitted from the new index, causing queries
      relying on the index to miss such rows. In installations that have
      enabled prepared transactions (max_prepared_transactions > 0), it's
      recommended to reindex any concurrently-built indexes in case this
      problem occurred when they were built.

      This is essentially a leak in the security restricted operation sandbox

      objects could parlay this leak to execute arbitrary SQL code as a
      superuser.

    + Fix usage of complex connection-string parameters in pg_dump,
      pg_restore, clusterdb, reindexdb, and vacuumdb (Tom Lane)

      The -d parameter of pg_dump and pg_restore, or the --maintenance-db
      parameter of the other programs mentioned, can be a connection string
      containing multiple connection parameters rather than just a database
      name.  In cases where these programs need to initiate additional
      connections, such as parallel processing or processing of multiple
      databases, the connection string was forgotten and just the basic
      connection parameters (database name, host, port, and username) were
      used for the additional connections.  This could lead to connection
      failures if the connection string included any other essential
      information, such as non-default SSL or GSS parameters. Worse, the
      connection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. (CVE-2020-25694)

    + When psql's \connect command re-uses connection parameters, ensure that
      all non-overridden parameters from a previous connection string are
      re-used (Tom Lane)

      This avoids cases where reconnection might fail due to omission of
      relevant parameters, such as non-default SSL or GSS options. Worse, the
      reconnection might succeed but not be encrypted as intended, or be
      vulnerable to man-in-the-middle attacks that the intended connection
      parameters would have prevented. This is largely the same problem as
      just cited for pg_dump et al, although psql's behavior is more complex
      since the user may intentionally override some connection parameters.

    + Prevent psql's \gset command from modifying specially-treated variables
      (Noah Misch)

      \gset without a prefix would overwrite whatever variables the server
