Hi, As discussed in default partition thread[1] <https://www.postgresql.org/message-id/CAFjFpRcvD-jf6z6-5mjx4tm-8NSj8Wnh%2B6%3DL6OB9Qy2yKX0HCg%40mail.gmail.com>, here is the patch to remove has_null from PartitionBoundInfoData structure. Basically flag has_null is not needed and null_index can be checked if the current bound is having a null value or not.
For simplicity of future use, in attached patch I have introduced a macro that would return TRUE if the given bound has null. PFA. [1]. https://www.postgresql.org/message-id/CAFjFpRcvD-jf6z6-5mjx4tm-8NSj8Wnh%2B6%3DL6OB9Qy2yKX0HCg%40mail.gmail.com Regards, Jeevan Ladhe
