how use pg_dump/pg_restore

Hi,
All ,

I am newbie to postgres database. How to take pg_dump from production
database and restore into development server using pg_restore..

>From documentation, I find that I have to use pg_dump for backup and
pg_restore for restoration.

My database name is otsdb..

For backup.I use command

Pg_dump otsdb > /home/Ketan/otsdbbkp.out

But after successfully dump.I can't see the otsdbbkp.out file in
/home/Ketan/

If I get otsdbbkp.out file then I copy this file on my development
server and then I issue the following command .

Psql -d otsdb -f otsdbbkp.out


(my development server database name is otsdb)

pl. help me..

If any thing wrong pl. guide me..
