[pgpool-hackers: 1614] Re: [pgpool-committers: 3261] pgpool: fix for 0000197: pgpool hangs connections to database..

[Tatsuo Ishii]

I think this fix is very important since typical configuration (there
are only two servers and on each server both pgpool-II and PostgreSQL
are running) easily triggers this problem. Maybe we should release new
minor versions soon. Let's discuss at today's dev meeting.

Best regards,
