From 17661188336c8cbb1783808912096932c57893a3 Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Sat, 20 Feb 2021 10:25:14 +0900 Subject: [PATCH] doc: Mention that partitions_{done,total} is 0 for REINDEX progress reports REINDEX has recently gained support for partitions, so it can be confusing to see those fields not being set. Making useful reports for for such relations is more complicated than it looks with the current set of columns available in pg_stat_progress_create_index, and this touches equally REINDEX DATABASE/SYSTEM/SCHEMA. This commit documents that those two columns are not touched during a REINDEX.
