The latest update on original bug report at Red Hat bugzilla shows that the
reproducer is just disable the peer access for 'postgres' user in
pg_hba.conf. So — the old server was most probably still running for OP
(not shut down properly as was originally said).
But basically, this fix is relevant to this thread so posting here.
