No, but existing sessions will carry on with whatever data they've read from the tzdata files; we don't have a provision to reload a timezone definition once read by a given process. Whether you use --with-system-tzdata doesn't matter; the same would apply if you were updating a Postgres-private copy of the tzdata files. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
