Pursuing that idea a bit further, was there a compelling original reason
the column in pg_proc had to be protrftypes and not just protransforms?
The transforms have been looked up at ProcedureCreate time.
Any PL that supports transforms has to repeat the transform lookups
if there are protrftypes present.
Any PL that doesn't support transforms needs only to check for presence
and say "sorry, I don't support those", which it could do just as easily
with a list of transforms as with a list of types.
