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.
