Use optimized bitmap set function for membership test in postgres_fdw Deparsing logic in postgres_fdw for locking, FROM clause (alias) and Var (column qualification) does not need to know the exact number of members involved, which can be calculated with bms_num_members(), but just if there is more than one relation involved, which is what bms_membership() does. The latter is more performant than the former so this shaves a couple of cycles.
