fix: drop replication slot causes postgres stuck on exit

[skyzh]

Problem

Fix #6969

Ref neondatabase/postgres#395 neondatabase/postgres#396

Postgres will stuck on exit if the replication slot is not dropped before shutting down. This is caused by Neon's custom WAL record to record replication slots. The pull requests in the postgres repo fixes the problem, and this pull request bumps the postgres commit.
