Right. I just took it out because it wasn't really that useful;
in general SQL-callable functions can expect that they're called in
fairly short-lived contexts, and so retail pfree's aren't very
interesting unless you're talking about large chunks.
BTW, just for the record, the "(void *)" casts were poor style
too IMHO --- DatumGetPointer() would be better.
