From 37851a8b83d3d57ca48736093b10aa5f3bc0c177 Mon Sep 17 00:00:00 2001 From: Peter Eisentraut Date: Mon, 14 Feb 2022 08:09:04 +0100 Subject: Database-level collation version tracking This adds to database objects the same version tracking that collation objects have. There is a new pg_database column datcollversion that stores the version, a new function pg_database_collation_actual_version() to get the version from the operating system, and a new subcommand ALTER DATABASE ... REFRESH COLLATION VERSION. This was not originally added together with pg_collation.collversion, since originally version tracking was only supported for ICU, and ICU on a database-level is not currently supported. But we now have version tracking for glibc (since PG13), FreeBSD (since PG14), and Windows (since PG13), so this is useful to have now.
