Hi Postgres Guru's,


Is it possible to use the Hot Backup (PITR Backup) of PostgreSQL on an Operating system to restore the database on other Operating system.


Thanks & Regards

Raghu

No, it isn't. Physical (PITR) backups are based on copying the physical files directly off the database server. The only way to move from one platform / architecture to another is to use a 'logical' method vs. the physical copy involved with PITR.

You other option is to use Slony. Create replica and in a short outage you can move master to replica.
