postgresql help

[Tom Allison <tom@tacocat.net>]

I'm at a road block...

I was reinstalling my hard drives to put in a RAID1 array.
The RAID/LVM stuff works 100%.

But somewhere I screwed up my postgresql-8.2 database installation.
I meant to set up the data directory on the RAID disk array
Unfortunately I deleted the /var/lib/postgresql/ directory and can't  
or don't know what to do to fix it.

No big deal, nothing invested, so I did a uninstall/purge on  
postgresql-8.2.
I reinstalled the database using aptitude (postgresql-8.2, postgres- 
client-8.2, libpq5) thinking that this would fix everything.

Nothing is happening.
No logs created to indicate if it works or not.
No directory created to show where the data directory is.
Nothing.

I'm just staring blankly at this.
I did a uninstall + purge and no errors reported.
I do a reinstall and NOTHING.

I've never experienced anything this blank before.

help?
