Hadi Moshayedi	86b12bc2d0	Always prefix operators with their namespace. (#2147 ) Previously we checked if an operator is in pg_catalog, and if it wasn't we prefixed it with namespace in worker queries. This can have a huge impact on performance of physical planner when using custom data types. This happened regardless of current search_path config, because Citus overrides the search path in get_query_def_extended(). When we do so, the check for existence of the operator in current search path in generate_operator_name() fails for any operators outside pg_catalog. This means that nothing gets cached, and in the following calls we will again recheck the system tables for existence of the operators, which took an additional 40-50ms for some of the usecases we were seeing. In this change we skip the pg_catalog check, and always prefix the operator with its namespace.	2018-05-05 13:27:26 -04:00
