package postgresql-8.4 8.4.4-0ubuntu10.04 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Binary package hint: postgresql-8.4

I tried to modify the place where postgresql date is mounted.
So I'm probably responsible for the original cause of the problem.

The real issue is that I cannot simply uninstall this package and resinstall it.
It keeps failing and blocks all other updates.

So I'll probably reinstall from scratch..

Note that this is an upgrade from Ubuntu 9.10.
