From cf3b46a0727366e00683421f45fbd6a228106b53 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Tue, 28 May 2019 14:16:29 -0400 Subject: [PATCH 4/6] Track collation versions for indexes. Record the current version of dependent collations in pg_depend when creating or rebuilding an index. That version is checked against current version whenever we call get_relation_info for an index or open the parent table during non-full VACUUM or ANALYZE. Warn that the index may be corrupted if the versions don't match. A new flag is added in RelationData to specify that the check has already beed done to avoid checking and reporting the message multiple time in a backend lifetime.
