Doesn't work very well for data types, for instance, since you'd lose any user-table columns of that type. The trick that seems to work fairly well (and ought to be better documented) is - dump version N database - create empty version N+1 database - install N+1's version of each needed contrib module into new database - restore dump, ignoring "object already exists" errors There is a TODO to figure out some cleaner way of handling this sort of thing ... 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
