Thanks. Yesterday I have put offcial release of pgpool 2.5 on
pgfoundry.org. The news release has not come up yet on the top page of
pgfoundry.org for some reason I don't know, but I hope it will appear
soon.
pgpool 2.5 has the capabilty to perform periodical health checking to
PostgreSQL.

If pgpool detects PostgreSQL failure, Slony should detect it as well,
no?
