An update that solves four vulnerabilities and has one security fix can now be
installed.

## Description:

This update for postgresql17 fixes the following issues:

Update to version 17.9 (bsc#1258754).

Security issues fixed:

  * CVE-2026-2003: improper validation of type "oidvector" may allow disclose a
    few bytes of server memory (bsc#1258008).
  * CVE-2026-2004: intarray missing validation of type of input to selectivity
    estimator could lead to arbitrary code execution (bsc#1258009).
  * CVE-2026-2005: buffer overrun in contrib/pgcrypto's PGP decryption functions
    could lead to arbitrary code execution (bsc#1258010).
  * CVE-2026-2006: inadequate validation of multibyte character lengths could
    lead to arbitrary code execution (bsc#1258011).

Regression fixes:

  * the substring() function raises an error "invalid byte sequence for
    encoding" on non-ASCII text values if the source of that value is a database
    column (caused by CVE-2026-2006 fix).
  * a standby may halt and return an error "could not access status of
    transaction".
