It should be around this time: https://www.postgresql.org/message-id/cab7npqrwvtqchweruf9o0hrrgfyq9xark7k7jclxqkly_6c...@mail.gmail.com And if I recall correctly the rason to not be able to reindex invalid entries was that when working on a table, schema or database, if a failure happens in the process, the reindexing would need to happen for a double number of indexes when repeating the command. -- Michael
