Re: Moving PostgreSQL data directory on Windows - Mailing list pgsql-general

Hi Otto,

The reason I didn't initialized a new cluster is because I was going to use
the old cluster that I have, just pointed the data directory to that
location in the installation and everything worked fine so I was able to
roll back to my 8.1.1 install from 8.1.2.

You can set the old location during the installation right in the initial
setup when it ask you what would like to install, where the PgAdmin, pl/java
section shows. Just highlight the Data Directory and click on browse, then
point to the location of your cluster.

Regards,

Jonel Rienton

Jonel,

I have initialized a new cluster in the installation (you did not), but that
should not have mattered, should it?

Best Regards,
Otto
