Ah right, I remembered that part, but not that *-scripts do conflict.

It doesn't say that it is needed for the initial installation as well.

From UX viewpoint, it would be nice if "apt-get install
postgresql-9.6-postgis-2.3" just worked. My idea would be:

Package: postgresql-9.6-postgis-2.3
Depends: postgresql-9.6-postgis-scripts

This means that each postgis N.N version can ship a new version of
-scripts which would then overwrite the older versions. Provided that
the *.sql files for older postgis versions are still shipped in newer
releases, users could even install older postgis extensions by using
the correct CREATE EXTENSION ... VERSION command. Unfortunately that's
not the case [1].

Or maybe all scripts packages should have Replaces: instead of
Conflicts:. (Though that doesn't scale I think)

Hrm. I'll try discussing that with the colleagues here, maybe they
have an idea.
