From 257836a75585934cc05ed7a80bccf8190d41e056 Mon Sep 17 00:00:00 2001 From: Thomas Munro Date: Mon, 2 Nov 2020 19:50:45 +1300 Subject: Track collation versions for indexes. Record the current version of dependent collations in pg_depend when creating or rebuilding an index. When accessing the index later, warn that the index may be corrupted if the current version doesn't match. Thanks to Douglas Doole, Peter Eisentraut, Christoph Berg, Laurenz Albe, Michael Paquier, Robert Haas, Tom Lane and others for very helpful discussion.
