postgresql-11 (11.22-1) unstable; urgency=medium

* New upstream version.

* This is expected to be the last PostgreSQL release in the 11.X series.
Users are encouraged to update to a newer release branch soon.

* 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.
(CVE-2023-5868)

* 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.
(CVE-2023-5869)

* 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)

* Rebase debian/patches/libpgport-pkglibdir.
