From 6bbc2f9b66104de67f29881c54e75fd6f5d2f694 Mon Sep 17 00:00:00 2001 From: Peter Geoghegan Date: Mon, 13 May 2019 15:39:05 -0700 Subject: [PATCH] Doc: Refer to line pointers as item identifiers. An upcoming HEAD-only patch will standardize the terminology around ItemIdData variables/line pointers, ending the practice of referring to them as "item pointers". Make the "Database Page Layout" docs consistent with the new policy. The term "item identifier" is already used in the same section, so stick with that.
