I'm trying to add some clarity to the rules I have on my tables. When a rule
is broken, I want to give a more informative message, so that the client
side can deal with it in a nicer manner. Right now I'm creating plpgsql
functions, and raising an exception in there with the customized text.
Is there a way to raise exceptions with regular SQL so that I don't have to
go to plpgsql?
Thanks,
Steve
