Subject: [PATCH] fix: handle 'connection reset by peer' in postgres test
 utility

Add 'connection reset by peer' to the list of errors that should trigger
starting a new postgres container in the test utility. This fixes flaky
tests that fail when PostgreSQL resets connections.

Fixes: https://github.com/coder/internal/issues/695
