Bug#749015: postgresql-9.3-postgis-2.1: Upgrade fails with liblwgeom-2.1.3.so conflict

[Ben Caradoc-Davies]

Package: postgresql-9.3-postgis-2.1
Version: 2.1.3+dfsg-2
Severity: important

Dear Maintainer,

apt-get dist-upgrade fails because libwlgeom-2.1.2 is not removed and conflicts
with  libwlgeom-2.1.3. Looks like this package upgrade relies on autoremove,
which can only be applied after the new package is installed. Perhaps you need
a Conflicts:?

The failure:

Workaround is:

apt-get remove postgresql-9.3-postgis-2.1 liblwgeom-2.1.3 liblwgeom-2.1.2
postgis

Followed by:

apt-get install postgresql-9.3-postgis-2.1

Kind regards,
Ben.
