Bug#883435: akonadi-backend-postgresql: akonadictl start fails with Postgresql 10 installed, likely needs a rebuild

[Diederik de Haas <didi.debian@cknow.org>]

Package: akonadi-backend-postgresql
Version: 4:17.08.0-1
Severity: important

Now that qt does support Postgresql 10 (#876421) I upgraded my
Postgresql packages to 10 and migrated the cluster (from 9.6).
After that I did 'akonadictl start' and noticed it was still using
Postgresql 9.6. So I purged that (and rebooted) and after that, akonadi
didn't want to start anymore. For some reason it's explicitly trying to
use pg_ctl from 9.6, but it should use the 10 version.

Konsole output:

$ akonadictl start
Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
org.kde.pim.akonadiserver: Could not start database server!
org.kde.pim.akonadiserver: executable: "/usr/lib/postgresql/9.6/bin/pg_ctl"
org.kde.pim.akonadiserver: arguments: ("start", "-w", "--timeout=10", "--pgdata=/home/diederik/.local/share/akonadi/db_data", "-o \"-k/tmp/akonadi-diederik.IOXa0T\" -h ''")
org.kde.pim.akonadiserver: process error: "execvp: No such file or directory"
org.kde.pim.akonadiserver: Failed to remove runtime connection config file
org.kde.pim.akonadicontrol: Application 'akonadiserver' exited normally...

So my guess is that akonadi-backend-postgresql needs to be rebuild so
that it gets linked to the current Postgresql version, which is 10 (in
both testing and sid).

(Even better would be if it would use the most recent version, but that
may be stretching it)

Cheers,
  Diederik
