Make get_extension_schema() available

Browse Source 
This routine is able to retrieve the OID of the schema used with an
extension (pg_extension.extnamespace), or InvalidOid if this information
is not available.  plpgsql_check embeds a copy of this code when
performing checks on functions, as one out-of-core example.
