An update that solves three vulnerabilities, contains one feature and has six
security fixes can now be installed.

## Description:

This update for postgresql, postgresql15, postgresql16 fixes the following
issues:

This update ships postgresql 16 (jsc#PED-5586).

Security issues fixed:

  * CVE-2023-5868: Fix handling of unknown-type arguments in DISTINCT "any"
    aggregate functions. 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.
    (bsc#1216962)
  * CVE-2023-5869: Detect integer overflow while computing new array dimensions.
    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. (bsc#1216961)
  * CVE-2023-5870: Prevent the pg_signal_backend role from signalling background
    workers and autovacuum processes. 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. (bsc#1216960)
