Describe the bug
The debian install doc states:

The easiest way to get started is to run timescaledb-tune, which is installed by default when using apt:

This statement is incorrect, as it is not installed by default when using apt. Here are all the files present in the timescaledb-postgresql-12 package:

timescaledb-tools is a package that is listed as a Recommends for our packages, so the default configuration of apt will install it when installing our packages. So I'm not sure this is actually a bug. I suppose we could clarify more, but not sure.

[phemmer]

I can check again with the new rc3 package, but when I reported this timescaledb-tools was not automatically installed.

@phemmer Any findings with 2.0-ga?
