      its input was of the expected data type.  Third-party extensions should
      check for similar hazards and add defenses using the technique intarray

    + Tighten security checks in planner estimation functions (Dean Rasheed)

      The fix for CVE-2017-7484, plus followup fixes, intended to prevent
      leaky functions from being applied to statistics data for columns that
      the calling user does not have permission to read.  Two gaps in that
      protection have been found.  One gap applies to partitioning and
      inheritance hierarchies where RLS policies on the tables should restrict
      access to statistics data, but did not.

      The other gap applies to cases where the query accesses a table via a
      view, and the view owner has permissions to read the underlying table
      but the calling user does not have permissions on the view. The view
      owner's permissions satisfied the security checks, and the leaky
      function would get applied to the underlying table's statistics before
      we check the calling user's permissions on the view.  This has been
      fixed by making security checks on views occur at the start of planning.
      That might cause permissions failures to occur earlier than before.

    + Prevent pg_dump scripts from being used to attack the user running the
      restore (Nathan Bossart)

      Since dump/restore operations typically involve running SQL commands as
      superuser, the target database installation must trust the source
      server.  However, it does not follow that the operating system user who
      executes psql to perform the restore should have to trust the source
      server.  The risk here is that an attacker who has gained
      superuser-level control over the source server might be able to cause it
      to emit text that would be interpreted as psql meta-commands. That would
      provide shell-level access to the restoring user's own account,
      independently of access to the target database.

      To provide a positive guarantee that this can't happen, extend psql with
      a \restrict command that prevents execution of further meta-commands,
      and teach pg_dump to issue that before any data coming from the source
      server.

      injection of psql meta-commands would also be possible this way.)

      reintroduced several cases.

    + Improve behavior of libpq's quoting functions (Andres Freund, Tom Lane)

      The changes made for CVE-2025-1094 had one serious oversight:
      PQescapeLiteral() and PQescapeIdentifier() failed to honor their string
      length parameter, instead always reading to the input string's trailing
      null.  This resulted in including unwanted text in the output, if the
      caller intended to truncate the string via the length parameter.  With
      very bad luck it could cause a crash due to reading off the end of
      memory.

      In addition, modify all these quoting functions so that when invalid
      encoding is detected, an invalid sequence is substituted for just the
      first byte of the presumed character, not all of it.  This reduces the
      risk of problems if a calling application performs additional processing
      on the quoted string.

    + Harden PQescapeString and allied functions against invalidly-encoded
      input strings (Andres Freund, Noah Misch)

      Data-quoting functions supplied by libpq now fully check the encoding
      validity of their input.  If invalid characters are detected, they
      report an error if possible.  For the ones that lack an error return
      convention, the output string is adjusted to ensure that the server will
      report invalid encoding and no intervening processing will be fooled by
      bytes that might happen to match single quote, backslash, etc.

      The purpose of this change is to guard against SQL-injection attacks
      that are possible if one of these functions is used to quote crafted
      input.  There is no hazard when the resulting string is sent directly to
      a PostgreSQL server (which would check its encoding anyway), but there
      is a risk when it is passed through psql or other client-side code.
      Historically such code has not carefully vetted encoding, and in many
      cases it's not clear what it should do if it did detect such a problem.

      This fix is effective only if the data-quoting function, the server, and
      any intermediate processing agree on the character encoding that's being
      used.  Applications that insert untrusted input into SQL commands should
      take special care to ensure that that's true.

      Applications and drivers that quote untrusted input without using these
      libpq functions may be at risk of similar problems.  They should first
      confirm the data is valid in the encoding expected by the server.

      If a CTE, subquery, sublink, security invoker view, or coercion
      projection in a query references a table with row-level security
      policies, we neglected to mark the resulting plan as potentially
      dependent on which role is executing it.  This could lead to later query

      negotiation (Jacob Champion)

      An error message received before encryption negotiation is completed

      server output.  Reporting it opens the door to various security hazards;
      for example, the message might spoof a query result that a careless user

    + Fix unintended interactions between SET SESSION AUTHORIZATION and SET

      The SQL standard mandates that SET SESSION AUTHORIZATION have a

      flawed, creating more interaction between the two settings than
      intended. Notably, rolling back a transaction that had done SET SESSION
      AUTHORIZATION would revert ROLE to NONE even if that had not been the
      previous state, so that the effective user ID might now be different
      from what it had been before the transaction.  Transiently setting
      session_authorization in a function SET clause had a similar effect. A
      related bug was that if a parallel worker inspected
      current_setting('role'), it saw none even when it should see something

    + 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.

      By itself, this fix will only fix the behavior in newly initdb'd

      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

      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
