Right, that's why the right answer for what you want to do is to have a trigger. I was just giving you an alternative since you didn't like the trigger answer.


Do you have a superuser account?  Pretty sure you gotta have that to
create lang.  OTOH, plpgsql is a "safe" language once installed, so
you should be able to ask your hosting provider to install it.  Can't

For plpgsql I don't believe it actually "installs" anything. The docs make it sound more like it activates it. So as long as you own your database you should be able to

createlang plpgsql
