Comment 3 for bug 833684

Reverse dependencies in main:

Just bacula, can easily be switched over to 9.1 (just like we did for 8.4 -> 9.0, it's just a dependency update). I can commit to uploading this.

Universe has a couple of server-side extensions which need to be updated to 9.1:
pgtap
postgresql-pllua
postgresql-plproxy
postgresql-plsh
skytools

Their Debian maintainers said that these would be updated in Debian soon, so we can just sync them as they land. This is the most risky bit, it might be that we will need to drop an extension if it cannot be built against/isn't available for 9.1 yet.

Aside from above, there are two more packages which have reverse dependencies, but aren't server side extensions:

Package: bucardo
Recommends: postgresql-plperl-8.4 | postgresql-plperl-9.0

-> This looks very questionable, and is probably just a trivial change to "Recommends: postgresql-plperl-9.1". The Debian maintainer is going to look into this.

Package: davical
Depends: [...] postgresql-client-9.0 | postgresql-client-8.4 | postgresql-client-8.3 | postgresql-client-8.2 | postgresql-client-8.1, [..]

This should just be fixed to "Depends: postgresql (>= 8.1)".

I can fix bucardo and davical if this is approved.
