Does JBoss ON 3.2 support discover/import/monitoring a postgresql instance?

Issue

• I have a host (RedHat 6.2 64bit) with postgresql (postgresql-9.2.4-1-linux-x64.run, free version of EnterpriseDB) and a JBoss ON agent installed. I'd like to add it for monitoring, but I don't know which plugin I need to install (and where to download from). I've tried the rhq-postgres-plugin-4.8.0.jar (rhq plugin). The plugin installation worked, by the discovering and manually adding didn't. When I try to add it, JBoss ON raises an exception (in log files), as follows:
