There isn't such a function. But you can use untrusted languages to do
this. I'm using plsh for this and send emails with my favorite MUA mutt.

You can send e-mails via pltclu or plperlu, more is also possible.

http://sourceforge.net/projects/pgmail/ <- This is tcl one.

plperlu one is attached. I don't remember where I got this one.

Typically this is bad idea. Better save the email info on a table and
fire a NOTIFY. An external daemon would be listening to that
notification, and send the email from the data in the table, which it
can subsequently delete or mark as used.

This is also better because you have a chance to retry if your SMTP is
down or whatever. If you fail to send the mail in a trigger or
function, you have no way to wait 10 minutes without clogging your
application.

If you still want to send e-mails directly from PG, you can try to use my
function based on pgmail which will allow you to send e-mail using
mailservers
which require authorization and analyze relpy from smtp to be sure your
e-mail is sent (look in attachment). You will need to install pltclu first.

PS: Maybe anyone knows how to send a unicode characters in e-mail using Tcl?

I wouldn't go so far as to say it's a bad idea(it really depends on what
you need to do).
I have been using a plperl based solution in a heavily used client
server application.

We don't send the emails via a trigger though, strictly initiated by a
procedure call from the client. Never had one single problem doing it
this way.

You wouldn't clog your application if you initiate the process through a
separate connection to the server which is initiated from a thread.

It certainly can be a very bad idea. Especially if the client that fires
the process is a web server.
