plpgsql isn't very bright about tuple descriptors containing dropped
columns.  The immediate problem is that compatible_tupdesc() doesn't
think a tupdesc containing one column matches one containing the same
column plus a dropped column; but fixing that would just allow
subsequent processing to crash :-(.  It needs a fair amount of work.
I think the other PLs are no better.
