Take a look at the LISTEN/NOTIFY interfaces in the docs. This will
allow async post-transaction processing. You can set up an ALSO rule
to notify when a particular type of statement has executed against
your target table.
http://www.postgresql.org/docs/8.0/static/sql-listen.htmlhttp://www.postgresql.org/docs/8.0/static/sql-notify.html
See the bottom of:

Hope that helps!
