You can check the arguments set for the postinst.  From memory this is:

postinst configure new-version

for a new installation and

postinst configure new-version old-version

for an upgrade.  Before using this, test it and check the documentation
in ftp.debian.org/pub/debian/doc/ It's written down somewhere.

You are able to do

if [ -f /etc/webalizer.conf ]

You are also able to put some magic code in that file in order to let
the postinst know that the file is not initialized.  This could be
done by adding


to the webalizer.conf file that you ship together with the package.

And as a third you can check against your default values if you know
that they won't make sense outside of 'default'.
