user removal in postrm

[Alexander GQ Gerasiov <gq@debian.org>]

Hi there.

I have the question about user removal in package's postrm script.

Is this correct?

I see the following scenario:

Package creates user for internal use only, and there will be no files
owned by this user left after package removal. In this case there will
be no problem if we remove user on package purge.

But some packages do not remove all files on removal. E.g. mailman or
mysql may leave it's databases, or torrent client (in system-wide
daemon mode) should not remove files it downloaded.
If such packages remove user, files will be owned by unnamed uid, and
this uid will be used by the next installed package.
I think this is not correct.

So what is the common way? I see nothing about this in Policy.
