* For this case, we could check pg_pltemplate, but that only works
* for languages, and does not help with function shared objects,
* so we just do a general fix.
*
* Some systems have plpython_call_handler() that references
* "plpython" defined in the "public" schema, causing pg_dump to
* dump it an generate an error on pg_dumpall restore; not sure
* on the cause, see:
