pg_dump is supposed to outout to stdout. you can redirect to a file using >

$ pg_dump dbname > /path/to/dumpfile.sql


Also is the database backup or are the tables and schemas backed up too.

it backs up everything in the database except large objects(lo)
(ignore it if u dont know understand lo)

what else do u expect it to backup if not tables and schemas?

Any restore
> command to be used .

$ psql -f dumpfile.sql
