SUSE 16.0 Important PostgreSQL Server Memory Threats 2026-20194-1

## This update for postgresql17 and postgresql18 fixes the following issues: Changes in postgresql17, postgresql18: Update to 17.7: * https://www.postgresql.org/about/news/postgresql-181-177-1611-1515-1420-and-1323-released-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 undersized buffer, which would then lead to writing past the end of the buffer.
