Please make sure you reply to the list too.
In your daemon you do something like: "LISTEN signal1", and in a trigger (say)
you issue "NOTIFY signal1". Your daemon will receive an asynchronoums message
"signal1" and you can then check the relevant tables for
updates/deletions/whatever signal1 means.
In practice, I usually don't care about responding that quickly, and just have
a cron job start up a script every 5 mins to check a "pending_jobs" table.
