I want to run postgresql 9.4 and 9.6 in parallel in jessie in order to

run postgis with my database so I also need the corresponding
postgresql-9.x-postgis packages. While postgresql-9.4,
postgresql-9.4-postgis-2.3, and postgresql-9.6 are available in
jessie/jessie-backports, postgresql-9.6-postgis-2.3 is *not*. Is there
any possibility to include postgresql-9.6-postgis-2.3 to
jessie-backports since this would greatly help many users who have to
upgrade their postgis enabled databases.
Another solution would be including postgresql-9.4-postgis-2.3 into
stretch, so that it is possible to run the old database after upgrading
to stretch. Currently the database becomes defunct after upgrade
because
the postgis libraries are missing.
The upgrade scenario is not supported by the Debian package, and is
unlikely to become supported.
The package in Debian is only build against a single postgresql version.
This problem with upgrades is a known issue, and is something is
upstream is working on but no solution is available yet.
If you have sufficiently large database that reimporting the data in new
database is not a viable option, you're better of building postgis
yourself.
Kind Regards,
