So from the sound of it, the connection methods I've been using are the 
exception rather than the rule.   Darn, it worked well for us.  :-(

What this would point to is NOT being able to use Slony-I for database server 
pooling for most web applications.   Yes?  Users should look to pgCluster and 
C-JDBC instead.

BTW, Tatsuo, what's the code relationship between pgPool and pgCluster, if 
any?
