How to restore backup database

[klo uo <klonuo@xxxxxxxxx>]

Hi,

I use PostrgrSQL 9.3 for couple of months now, on Windows.

I installed new Window OS, and before installing, I made tar backups of my PostgreSQL databases.

Now I want to restore these on my new OS, but I can't find such option in pgAdmin.

In documentation (http://www.postgresql.org/docs/9.3/static/backup.html) I see only suggestions how to restore sql dumps with command line tools, but none how to restore single file tar backups.

Please suggest the right way to restore my backup databases.

Thanks
