regardless of the current schema search path. Since CREATE OPERATOR CLASS only allows one default opclass per datatype regardless of schemas, this should have minimal impact, and it fixes problems with failure to find a desired opclass while restoring dump files. Per discussion at http://archives.postgresql.org/pgsql-hackers/2006-02/msg00284.php. Remove now-redundant-or-unused code in typcache.c and namespace.c, and backpatch as far as 8.0.
