Upstart script for pgagent on Ubuntu...

Has any one produced an Upstart script for pgagent on Ubuntu? I tried with the following:

<code>
description "Pgagent process control script"
author "Me"

start on started-postgres
stop on stopped-postgres

expect daemon
respawn

script
su - postgres
pgagent "dbname=postgres user=postgres"
end script
</code>

I also added an 'initctl emit started-postgres' to the pogstres-8.4 init.d and script and the corresponding stopped-postgres.

Whether I specify 'expect daemon', 'expect fork', or nothing, the command 'sudo initctl start pgagent' hangs at the command line and doesn't start the daemon. The stop command hangs also.

The 'pgagent "dbname=postgres user=postgres"' works normally if issued from the terminal prompt. I know the command is supposed to be issued from a normal user account, but shouldn't the su- command accomplish that?
