Обсуждение: pgsql: Preserve replica identity index across ALTER TABLE rewrite
Preserve replica identity index across ALTER TABLE rewrite If an index was explicitly set as replica identity index, this setting was lost when a table was rewritten by ALTER TABLE. Because this setting is part of pg_index but actually controlled by ALTER TABLE (not part of CREATE INDEX, say), we have to do some extra work to restore it.
