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.
OK, I think (after a bit of playing) I see what you mean.
If I do the following:
CREATE TYPE tt AS (id int);
CREATE OR REPLACE FUNCTION sel_test2() RETURNS tt AS $$
...
Then it all works OK, because the SELECT inside the function is
returning one int and so is the function.
