Because the "other" database which I would like to keep in sync is a MySQL db. Furthermore I do not need a 1:1 replica, but instead just update a few columns in different tables there. My inital plan was to add a timestamp-column which is updated at every Update and to poll for changes every 5-10s. However, the word "polling" seems to cause an allergic reaction for some poeple ;) Thanks, Clemens -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
