Operating system:   Vista SP1
Description:        Uninstall : impossible to delete some files (base...)
Details:

Impossible to delete :
C:\Program Files\PostgreSQL\8.3\data\base\17179

I think it's due to a security problem, but I am the administrator of my
computer and network.

What can I do ?

I am sure it's due to a too quickly development of your application : with
ayware we don't have such problems. I was testing PostGre, and I am sure I
won't install it anymore, if I have such problem to uninstall it.
