I'm please to announce the release of a small tool, pgnotifyd:
http://www.pogo.org.uk/~mark/pgnotifyd/
pgnotifyd connects to a PostgreSQL database, listening for the named
asynchronous notification. When notification is received it executes the
given command.
It is typically a cleaner and more efficent alternative to polling a
PostgreSQL database for changes (using a crontab(5) or similar.)
I've been using it successfully to synchronise passwords and mailing
lists. This is an initial release in the hope others can benefit from it.
