Will do after postgis is updated.

The postgresql specific dependency has a long history (since #559604 at
least). While not ideal, having the Recommends for both postgis (for the
executables) and postgresql-9.4-postgis-2.1 (for the shared library) is
useful I think as postgis only Suggests postgresql-9.4-postgis-2.1.

Providing a virtual postgis-extension package was discussed briefly back
in April. That was in the context of TinyOWS which also doesn't need an
explicit PostgreSQL version specific dependency. But nothing concrete
has come out of this yet.

I think the postgis-extension virtual package without a postgres
specific version is the way to go for cases like osm2pgsql and tinyows.

For now I think we should stick to bumping the postgresql version when
the default changes, while acknowledging that this is very suboptimal.

Kind Regards,

Bas
