[pgpool-committers: 262] pgpool: Fix detect_postmaster_down_error to handle failover properly.

[Tatsuo Ishii]

Fix detect_postmaster_down_error to handle failover properly.  It is
possible that it fails to read backend socket after detecting backend
errors and before actually detaching the backend. In this case we
should close this session. Otherwise continue to read the down backend
socket.
