My recollection is that I was not nearly as worried about short-term
pallocs in the plpgsql code itself, as about leakage in various main-
backend routines that get called incidentally during parsing.
backend/parser/ is quite cavalier about this as a whole, because it
expects to be called in contexts that are not long-lived. Have you
done any checking to ensure that the per-function context doesn't get
unreasonably bloated this way?
