Can't you do this today in about three lines of your favourite scripting language? I used to do this in perl on Oracle and that was without anything like LISTEN/NOTIFY to optimize it. Web pages just inserted a record and went on about their business while a worker daemon scanned for new records and generated notification mails. The problem with trying to push everything into the database is that it ends up sucking your entire application into the database. That limits your choice of languages and tools, and also creates a huge bottleneck. -- greg -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
