You could write a function in a language like plperlu, pltclu, or
plpython, but a problem with functions that have effects outside
the database is that those effects can't be undone if the transaction
rolls back.  A common example is a trigger that sends email when a
table is changed: if the trigger fires and then you roll back the
transaction, it's too late to cancel the email.  Depending on what
you're doing it might be better to use LISTEN/NOTIFY and have a
client program send email when it receives a notification (notifications
are sent only when the transaction commits).
