Follows all the results:

What does the directory listing for /var/lib/pgsql/9.6/data show?
[root(at)localhost data]# pwd

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).

[root(at)localhost 9.6]# du -hs *
0 backups
4,2G data
4,0K initdb.log

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

systemctl start postgresql-9.6.service
Job for postgresql-9.6.service failed because the control process exited
with error code. See "systemctl status postgresql-9.6.service" and
"journalctl -xe" for details.

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.
