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, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
