[pgpool-committers: 8494] pgpool: Enhance error message while processing parse message.

[Tatsuo Ishii]

Enhance error message while processing parse message.

In non-streaming replication mode, a sync message is sent to backend
after a parse message is sent to backend, expecting to get a ready for
query message.  If different message is returned, pgpool will complain
that. This commit adds more information: the message kind returned and
the backend node id.
