Hi folks,I've been seeing some curious behaviour on a postgres server I administer.Intermittently (one or two times a week), all queries on that host are simultaneously blocked for extended periods (10s of seconds).The blocked queries are trivial & not related to locking - I'm seeing slowlogs of the form:`LOG: duration: 22627.299 ms statement: SET client_encoding='''utf-8''';`
