Right. I was thinking about a "Darn I didn't read the release notes
case and really wanted to make a backup with the old version first" kind
of abort option. Something like detecting /var/lib/firebird/1.5
or /var/lib/firebird2/data. I remember reading somewhere the proper way
to upgrade is to make an backup with the old version, and restore with
the new. Or is the server always backwards compatible with an old ODS?
Not sure here.

Right. Now I am more sure. And it's for bonus points :)
