Comes with what server install? It depends on how you install PostgreSQL, and on what platform you are. But clearly you are using a pg_dump that comes from a previous version. It could be that you have both installed, but that the 8.3 version comes first in your PATH perhaps? > the first one I backup using pgAdmin III ver. 1.8.4 on a ver 8.3.9 postgreSQL > server pgadmin ships with a copy of pg_dump. 1.8 ships with pg_dump from 8.3, so -i should work there. pgadmin 1.8 isn't supported with server 8.4 at all anyway, so you need pgadmin 1.10 for that - which ships with pg_dump from 8.4. > the second one I backup using command line on a ver 8.4 postgreSQL server > Is this something that can solved by upgrade or reinstall ver. 8.4 of > pg_dump? > Is that its only downward compatible but not upward? which mean I can do > restore on 8.4 from backup created by ver 8.3 pg_dump, but probably won't > work the other way around?

And due to the fact that it's not really useful, it's been removed (well the option is there, but it doesn't do anything) in 8.4. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
