pgsql: Fix REASSIGN OWNED for text search objects

Fix REASSIGN OWNED for text search objects

Trying to reassign objects owned by a user that had text search
dictionaries or configurations used to fail with:
ERROR: unexpected classid 3600
or
ERROR: unexpected classid 3602

Fix by adding cases for those object types in a switch in pg_shdepend.c.

Both REASSIGN OWNED and text search objects go back all the way to 8.1,
so backpatch to all supported branches. In 9.3 the alter-owner code was
made generic, so the required change in recent branches is pretty
simple; however, for 9.2 and older ones we need some additional
reshuffling to enable specifying objects by OID rather than name.

Text search templates and parsers are not owned objects, so there's no
change required for them.
