Hi folks,

I've run into an issue that I'm sure there's a fix for, I just haven't
quite figured it out on my own.

First the overview of the environment:
	Linux (CentOS release 4.2)
	Tomcat 5.x application server
	Struts/Tiles MVC
	Hibernate 3.1 Object Persistence
	postgresql-8.2dev-500.jdbc2.jar for JDBC drivers

What I'm seeing is the first time my web application is being run there
is a bunch of processes running around that look like:
"postgres: peter peter_trialdb 127.0.0.1(46222) idle"

I presume you mean "idle in transaction"

in the process table.  What's worse, is if I try to modify my database
schema while these processes are running (and they seem to stick around forever) the psql session running the SQL script to do the modifications
hangs on the first statement that modifies or drops an existing table.

I'm not even sure what part of this puzzle is the root cause of the
problem. JDBC drivers? Hibernate configuration? Elvis?
It's the pooling implementation, it should be setting autocommit to true when closing the connection, which really means returning the connection to the pool.

Any insight is welcome and appreciated.

Dave
