BUG/MINOR: checks: Fix PostgreSQL regex on the authentication packet

For PostgreSQL health check, there is a regex on the backend authentication
packet. It must match to succeed. But it exists 6 types of authentication
packets and the regex only matches the first one (AuthenticationOK). This patch
fixes the regex to match all authentication packets.

No backport needed.
