The explanation is doubtless here:
2004-09-19 19:38 tgl
* src/pl/plpython/plpython.c: Add defenses against plpython
functions being declared to take or return pseudotypes. Not sure
why I neglected to add these checks at the same time I added them
to the other PLs, but it seems I did.
It's certainly possible to weaken this test to allow "void" again,
but shouldn't there be corresponding changes elsewhere to ensure that
the behavior is actually sensible?
