Backend database backup/move on Linux/Unix

[kkpro]

Hello. Seems to be there is another quiz from HP when using internal backend db, so PostgreSQL. While there are several manuals about it since SIM version 5, I couldn't do nothing according to them. Not very familiar with Postgres, but the latest 7.1 manual says for example "you must use pg_dump version higher than 8.4", while Postgres version using by 7.1.1 SIM is 8.2 !

On every command listed in manual (so, this pg_dump, createdb, createuser etc..) I got an error

"too many command-line arguments.. ".

Any ideas ?
