From d69c404c4cc5985d8ae5b5ed38bed3400b317f82 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Wed, 22 Mar 2023 18:31:52 +0900 Subject: [PATCH] doc: Add description of some missing monitoring functions This commit adds some documentation about two monitoring functions: - pg_stat_get_xact_blocks_fetched() - pg_stat_get_xact_blocks_hit() The description of these functions has been removed in ddfc2d9, later simplified by 5f2b089, assuming that all the functions whose descriptions were removed are used in system views. Unfortunately, some of them were are not used in any system views, so they lacked documentation. This gap exists in the docs for a long time, so backpatch all the way down.
