[Pgpool-general] pgpool not working with one of the db server upgraded from 8.4.4 to 9.0.4

Thu Apr 28 23:36:24 UTC 2011

Hi,

You should not mix different major version of PostgreSQL.  If you
upgrade master DB to 9.0.x, your problem should go away.

> Hi,
> 
> We are running pgpool 3.0.1 on a host with two other independent db
> servers.  It (psql) works for a long time with both db servers are
> running postgresql 8.4.4.  However, when we updated the secondary db
> server to 9.0.4 yesterday, the 'psql' is not working anymore (see
> below for the logs)
> 
> I tried to disconnect the 2nd db server (9.0.4) and restart the pgpool
> (in failover mode, connect to 1st db server 8.4.4), and in this case,
> 'psql' has no problem.
> 
> Is this related to postgresql 9.0.4 or something else that I did wrong
> ?
