## Description:

This update for postgresql17, postgresql18 fixes the following issues:

Changes in postgresql18:

  * Fix build with uring for post SLE15 code streams.

Update to 18.1:

  * https://www.postgresql.org/about/news/p-3171/
  * https://www.postgresql.org/docs/release/18.1/
  * bsc#1253332, 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#1253333, 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.

  * pg_config --libs returns -lnuma so we need to require it.

Update to 18.0:

  * https://www.postgresql.org/about/news/p-3142/
  * https://www.postgresql.org/docs/18/release-18.html

Changes in postgresql17:

  * https://www.postgresql.org/about/news/p-3171/
  * https://www.postgresql.org/docs/release/17.7/
  * bsc#1253332, 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#1253333, 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
