Just noticed it's a SETOF[] function.  Which makes it odd that I can
call it in the target list at all, but explains the row restriction.

It's still confusing behavior (three regulars on IRC thought it was a
bug too) and users should be warned in the documentation.  Not sure
exactly where, though ... maybe in 9.7?
