Hi All

We are running an old version of PostgreSQL on a Linux Server.
We have created a few databases on the file system defined in the postgresql.conf, but now I would like to create another database within the same cluster but on a different file system.
Is this possible and if so, how do we go about it.

In a nutshell:

I have the following statement defined in the postgresql.conf file - data_directory = '/opt/pgdata_postgres'

I have created the following database datadb1, datadb2 (plus all default databases)

Now I want to create a third database datadb3, but it needs to be created on file system "/opt/pgdata1_postgres"  and not on '/opt/pgdata_postgres'

Is this possible

Regards
Ian

Hi Ian,

Tablespaces would work... take a look:

Best,
Tim
