Well, my standard answer to that would be "your WHERE clause should
select on a primary key (which could be multiple columns)".
We're pretty constrained in changing the semantics of plpgsql, because
the raison d' etre of that language is to emulate Oracle's (TM) PL/SQL
(TM), warts and all.
(Now, if you can show us that PL/SQL behaves differently in that
situation, we'll definitely be willing to change plpgsql.)
