Re: easy one: location of the database cluster

Hi,

Looks like I should get to know the "Filesystem Hierarchy Standard" atleast
a little better.

This is partly my concern also. It's only a concern for me because I don't
have any direct experience of managing and upgrading production systems
using packages, I have always used the source code download. Backing up your
databases before an upgrade is always advisable, but on the other hand, we
typically don't want to have to endure a restore just because we messed up a
minor upgrade. if you are building from source it's no problem as you just
don't run initdb. As to package upgrades, presumably they don't touch your
data. I have to write a manual for the maintenance and updating of the
server, so I'm gonna have to test it all anyway.

Getting back to my original question (as I think it was) I havn't seen any
reason not to use the default data directory used by the package, especially
if it conforms with the above mentioned standard.
