Bug#535577: debian-policy: what to do with user-generated data (databases) on purge

shoudl try to protect users like me from themselves liek this, and at
least _ask_ before removing databases (and other data).

I think it shouldn't delete databases at all.
Asking is just another opportunity for the user to make a mistake.

see it is still available) in the postinst.

Is it? I think there's quite a sensible 'default': don't delete.
The number of prompts (and complexity of scripts) should be kept minimal.
