Something _like_ that is possible.
you can also do it directly with a trigger if you prefer:
CREATE TRIGGER alert_insert AFTER INSERT OR UPDATE ON alert FOR EACH ROW EXECUTE PROCEDURE alert_notify();
Where the alert_notify() function would then call pgmail() with a meaningful subject and body etc -- see below
What I would do instead is for the trigger to cause a record to be put into a table that might be called something like "submit_email".
An asynchronous process (that might look for NOTIFY requests!) would
then rummage thru submit_email to find messages it needs to send.
at which point you could then use pgmail() to send the email
