An update that solves two vulnerabilities can now be installed.

## Description:

This update for postgresql16 fixes the following issues:

Security fixes:

  * CVE-2025-12817: Missing check for CREATE privileges on the schema in CREATE
    STATISTICS allowed table owners to create statistics in any schema,
    potentially leading to unexpected naming conflicts (bsc#1253332)
  * CVE-2025-12818: Several places in libpq were not sufficiently careful about
    computing the required size of a memory allocation. Sufficiently large
    inputs could cause integer overflow, resulting in an undersized buffer,
    which would then lead to writing past the end of the buffer (bsc#1253333)

Other fixes:

  * Upgrade to 16.11
