Sometimes I need some external action to be taken when a table is updated. I
can't find anything about how to do this with triggers.
The easiest would be to have a server listening on a port. But can I write a
PL/pgSQL trigger that can talk tcp/ip?
There is a short description about untrusted Perl. This might solve the
problem of talking to the port, but I'm not sure I would like to run anything
called "Untrusted" in my server!
