Ensure you actually have a folder named "/var/lib/pgsql/9.6/data" with your
database in it (not, possibly, a folder named "date" per your original
message).

as root:

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

If it still won't start after that, please do an "ls -alRZ
/var/lib/pgsql/9.6", pastebin the output, and send the link.
