Well, there ought to be *some* way to tell PL/pgSQL to discard the result. Right now I am adding a variable to select
intobut never otherwise use. Inelegant, IMHO. Perhaps I’m missing some other way to do it?
If so, it would help if the hint suggesting the use of PERFORM pointed to such alternatives.
