Обсуждение: pgsql: Remove "convert 'blah' using conversion_name" facility, because

Log Message:
-----------
Remove "convert 'blah' using conversion_name" facility, because if it
produces text it is an encoding hole and if not it's incompatible
with the spec, whatever the spec means (which we're not sure about anyway).

It's not critical, but just for future reference, you forgot to bump
catversion here.  Which you should've because adding/removing built-in
functions renders the backend incompatible with the system catalogs.
