postgresql backup and restore needed

postgresql backup and restore needed, for a postgres 8.4 server on CentOPS Must be familiar with pg_dump and pg_dumpall The backup should be 3 files, one of those a tar with multiple files. 1. [login to view URL] - with the grants for a particular user 2. cat [login to view URL] - with the postgresql users and encrypted password 3. a tar file, one for each database - the tar should contain #.dat files, a [login to view URL] file, and a [login to view URL] file, to create the tables and import the data. I will provide a sample backup to work with.
