From a6cd1fc692eff708fd42c72b03f756fa1860530e Mon Sep 17 00:00:00 2001 From: Amit Kapila Date: Mon, 27 Feb 2023 08:32:45 +0530 Subject: [PATCH] Change xl_hash_vacuum_one_page.ntuples from int to uint16. This will create two bytes of padding space in xl_hash_vacuum_one_page which can be used for future patches. This makes the datatype of xl_hash_vacuum_one_page.ntuples same as gistxlogDelete.ntodelete which is advisable as both are used for the same purpose.
