Bumps org.postgresql:postgresql from 42.2.12 to 42.7.11.

Release notes

Sourced from org.postgresql:postgresql's releases.

v42.7.11

Security

fix: Limit SCRAM PBKDF2 iterations accepted from the server. pgjdbc was vulnerable to a client-side denial of service in SCRAM-SHA-256 authentication, where a malicious or compromised PostgreSQL server could specify an extremely large PBKDF2 iteration count, causing the client to consume unbounded CPU and potentially exhaust connection pools. The fix introduces a new scramMaxIterations connection property (defaulting to 100,000) to cap iteration counts before computation begins. See the Security Advisory for more detail. The following CVE-2026-42198 has been issued.
