Re: How to move a database from HP server to Linux Server that had already one database.

Hi Kevin,

If I use the :
Origim: pg_dump -Ft -b db_name > file.tar
Target: pg_restore -d new_db file.tar

The target server has a db, using PGDATA=/postgres, the same in the other server... There is any risk to lost any data?

I am not sure if I can do it in this way.. As the are in diferent servers and network.

I found a paper that suggest to use pg_dump -Ft -b db_name > file.tar .... Transfer it to new server and you ther the pg_restore -d new_db file.tar But as the servers have different SO.. I am not sure if it can be used...

And another question is that in the target server there is a database there that we can not destroy.

Thanks for your help.

I usually pipe the output of pg_dump to psql, and thereby avoid making a copy of the dump output entirely. If you want to dump in custom format, yeah, you would use pg_restore instead.
