You are now connected to database "fapforum" as user "pgsql".

 prsd_end
 prsd_lextype
 prsd_start
 thesaurus_init
(4 rows)

There *should* be a pg_catalog.prsd_end built-in function, but it's
going to have null probin.  I think you're being careless about
schema names here.

fapforum=# \df prsd_end;
                            List of functions
   Schema   |   Name   | Result data type | Argument data types |  Type
------------+----------+------------------+---------------------+--------
 pg_catalog | prsd_end | void             | internal            | normal
(1 row)

This does not prove that there's not a, say, public.prsd_end.  Try
"\df *.prsd_end" to see all the functions by that name.

You are correct.  Thanks; got it.  (That's what I get for not being specific)

One more question - for safety do I also need to drop all the other previously-declared public functions such as rank*() (in all its forms) and concat even thought they do not reference the shared library, or are they safe to leave there?  I see there are pg_catalog copies of these as well....
