It's not, but chkpass_rout is declared to return text, so it should be
saying PG_RETURN_TEXT_P. It turns out both macros do the same thing,
so this is just a cosmetic issue.

That is odd. You only have the chkpass operators shown in the contrib
module, right? No "chkpass = chkpass" operator? Without one, vacuum
analyze should pretty much ignore the chkpass column ...
