Make get_extension_schema() available

michaelpq · michaelpq · commit e20b1ea1575c · 2023-03-07T14:18:20.000+09:00
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.
