I suspect this could be a systemd problem. What if you try to manually
start the postgres instance?

pg_ctl -D /data/postgresql/data start

What happens then?

This is of course to prevent you to destroy your system.
I would remove the link, create it to an empty directory and then
initdb such directory as if it is your new database. I imagine that
would start, in such case your data directory is wrong. Can you show
us the content of /data/postgresql/data?
