Yeah, otherwise you'll get a very confusing message about too many
columns in a *table*.
Also, there are two levels we have to check at, per-function and
then the merged tupdesc for the whole RTE.
I should have thought of function RTEs when asserting that there
were no other holes to plug :-(. Will fix, thanks for the report!
