What is the use of the existing behavior?  You get back an arbitrary
implementation dependent value.  We don't even guarantee what the value
will be.  If we changed it to return a different implementation
dependent value, would users get upset?

No they would not get upset because they wouldn't know.

Can we just do the right thing?

I'm in favour of fixing this, and update the documentation.

+1. I'd say that if users complain we can always create an extension (on PGXN) that offers the old behavior. Users could even put that function before pg_catalog in search_path and get the old behavior back.
