I've look throught the docs and from what I can see the bellow code should
work, however I keep getting the error:
ERROR: parser: parse error at or near "$" at character 53
CREATE FUNCTION session_update() RETURNS trigger AS $session_update$
BEGIN
-- Check date exists
IF NEW.stamp_lastupdate IS NULL THEN
NEW.stamp_lastupdate := 'now';
END IF;
RETURN NEW;
END;
$session_update$ LANGUAGE plpgsql;
CREATE TRIGGER session_update BEFORE INSERT OR UPDATE ON sessions FOR EACH
ROW EXECUTE PROCEDURE session_update();
Any help or suggestions of websites I should read would be appercated.

Which version of postgresql are you using? I don't believe that the "$" quoting
was available in older versions than 8 (or late 7?).

I don't think that it worked then. Simple test:
CREATE FUNCTION session_update() RETURNS trigger AS '
BEGIN
-- Check date exists
IF NEW.stamp_lastupdate IS NULL THEN
NEW.stamp_lastupdate := ''now'';
END IF;
RETURN NEW;
END;
' LANGUAGE plpgsql;

It didn't error out, however the function didn't work. Specificly the if
statement. I took out the if statement and it started updating, I put it
back in and it fails to update. Not sure why. I've confirmed that the
program not attempting to update the stamp_lastupdate field. Here what I
end up with that worked.
CREATE or REPLEACE FUNCTION session_update() RETURNS trigger AS '
BEGIN
-- Check date exists
NEW.stamp_lastupdate := ''now'';
RETURN NEW;
END;
' LANGUAGE plpgsql;
CREATE TRIGGER session_update BEFORE INSERT OR UPDATE ON sessions FOR EACH
ROW EXECUTE PROCEDURE session_update();
I appercated the help Bricklen.

the $ quoting is available since 8.
This seems bad to me also:

I think it should be:
CREATE FUNCTION session_update() RETURNS trigger AS $$
[..function body..]
$$ LANGUAGE plpgsql;

No, the identifier between the $$ is legit, providing you're at v8 and above.
