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.
