Hi Hubert,

the issue is likely this:

Package: postgis
Version: 3.0.2+dfsg-4.pgdg100+1
Recommends: postgresql-13-postgis-3, postgis-doc

If you have "install recommends" activated in the apt config (the
default), then installing "postgis" will also install the recommended
packages.

Compare:

$ sudo apt install postgis
Die folgenden NEUEN Pakete werden installiert:
  postgis postgis-doc postgresql-13 postgresql-13-postgis-3 postgresql-13-postgis-3-scripts
  postgresql-client-13

$ sudo apt install --no-install-recommends postgis
Die folgenden NEUEN Pakete werden installiert:
  postgis

I think we can change that to "Recommends: postgresql-postgis", will
do so for the next version.

Christoph
