[Pkg-postgresql-public] Bug#846656: [postgresql-9.6] When installing, default cluster "9.6/main" is not created.

[Leandro Doctors]

Package: postgresql-9.6
Version: 9.6.1-2
Severity: important

--- Please enter the report below this line. ---

Dear maintainer,

I had to manually run

#pg_createcluster --start 9.6 main

to make the server work. Otherwise, it will start but will not listen
to any connections.

At first, I experienced this when installing the "postgresql" package
(which, in turn, depends on "postgresql-9.6").
So, I thought it was a "postgresql" package problem.
Therefore, I purged both "postgresql" and "postgresql-9.6" and
re-installed "postgresql-9.6" (and later, "postgresql").
In both cases, after each case I had to manually create the cluster.

As a side note, it would be nice to be prompted for the name of the
cluster when installing the package.

Thank you in advance for your time on this problem,
Leandro
