    * Fix handling of unknown-type arguments in DISTINCT "any" aggregate
      functions (Tom Lane)

      This error led to a text-type value being interpreted as an unknown-type
      value (that is, a zero-terminated string) at runtime.  This could result
      in disclosure of server memory following the text value.

      The PostgreSQL Project thanks Jingzhou Fu for reporting this problem.

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

      When assigning new elements to array subscripts that are outside the
      current array bounds, an undetected integer overflow could occur in edge
      cases.  Memory stomps that are potentially exploitable for arbitrary
      code execution are possible, and so is disclosure of server memory.

      The PostgreSQL Project thanks Pedro Gallegos for reporting this problem.

    * 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.

      The PostgreSQL Project thanks Hemanth Sandrana and Mahendrakar
      Srinivasarao for reporting this problem. (CVE-2023-5870)

    * 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.

    + Disallow substituting a schema or owner name into an extension script if
      the name contains a quote, backslash, or dollar sign (Noah Misch)

      This restriction guards against SQL-injection hazards for trusted
      extensions.

      The PostgreSQL Project thanks Micah Gate, Valerie Woolard, Tim
      Carey-Smith, and Christoph Berg for reporting this problem.
      (CVE-2023-39417)

    + Fix MERGE to enforce row security policies properly (Dean Rasheed)

      When MERGE performs an UPDATE action, it should enforce any UPDATE or
      SELECT RLS policies defined on the target table, to be consistent with
      the way that a plain UPDATE with a WHERE clause works.  Instead it was
      enforcing INSERT RLS policies for both INSERT and UPDATE actions.

      In addition, when MERGE performs a DO NOTHING action, it applied the
      target table's DELETE RLS policies to existing rows, even though those
      rows are not being deleted.  While it's not a security problem, this
      could result in unwanted errors.

      The PostgreSQL Project thanks Dean Rasheed for reporting this problem.

    + 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)
