I have prepared a package for this module that allows PyGreSQL (and
possibly other adapters) to use NOTIFY/LISTEN in PostgreSQL. Anyone
have any problem with me importing it? The package can be seen at
I'm sorry to bug everyone with these questions but I am not actually
part of the pkgsrc team so I don't want to import things without getting
pgnotify is a PostgreSQL client-side asynchronous notification handler
Python and PyGreSQL.
Typically, asynchronous notification is used to communicate the message
changed this table, take a look at it to see what's new" from one
client to other interested PostgreSQL clients.
A useful programming technique is to generate asynchronous notification
rule that is triggered by table updates; this way, notification happens
automatically when the table is changed and the application programmer
accidentally forget to do it.
At present, pgnotify works with PyGreSQL only. It should work with PoPy
psycopg when those modules provide Pythonic interfaces to additional
PostgreSQL client-side functions, as described in the README.
