Now I'm wondering about stray entries in pg_cast.  Also,
do you have any extensions loaded in that DB that aren't
in your other ones?

Our databases are deployed with automation tools.  They should all be created the same.  They all have the same 17 extensions.  I've asked a DBA to confirm.

This issue only appears in the function I have listed.  A similar function, same contents and parameter but with a different name, works the way I would expect.

D'oh, actually this would have complained if there was more
than one match, so that theory is wrong:

Now I'm wondering about stray entries in pg_cast.  Also,
do you have any extensions loaded in that DB that aren't
