Laurenz,
For sure there's all the necessary files in '/data/postgresql/data'. The startup process cannot read it, because of sym
link.
Executing init-db return the below message:
>>>> # sudo postgresql-setup initdb
Data directory is not empty!

So there is some "postgresql-check-db-dir" (not part of PostgreSQL) that complains that there is nothing in
/data/postgresql/data. Is that accurate?
It looks like you succeeded in getting the startup process to look for the PostgreSQL data directory in the new
location,but - alas - there is no data directory there yet.
You could follow the instructions and run "initdb" to create the data directory.
Yours,
