Yes, that should work fine. See the doc pages for LISTEN and NOTIFY:
http://www.postgresql.org/docs/current/static/sql-listen.html
http://www.postgresql.org/docs/current/static/sql-notify.html

Along with the link I sent earlier to the psycopg2 section, assuming
you are in fact using psycopg2 as your database connector. I suggest
trying out the psycopg2 example in their docs verbatim first, then
adapting the example to your own code.
