So why not try:

chown -R postgres:postgres /var/lib/pgsql/9.6/data

on the previous system. Not sure if is was a transcribing error, but in
your previous post you had:

Chown -R postgres: postgres /var/lib/pgsql/9.6/data

which would not work.

Just to be clear we are talking about the data/ directory.

Could we see the listings for data/ data_old?
