Tom,

But it's already disallowed in most places. The i = i + 1 seems to be an
exception.
So what happens to "i" if I do:
IF i = i + 1 THEN ....
does "i" increment? If so, isn't that a bug?
I don't think too many people are using that functionality intentionally; I
probably write more PL/pgSQL than anyone and would regard any assignment
without ":=" as a bug.
