Hi,
There was a disaster in my development note. I was able to recover the
data folder. PostgreSQL 9.6.2, was installed in Centos 7.
Here are the procedures I'm trying to initialize Postgresql for me to do
a backup.
1- I installed PostgreSQL 9.6.2 on a VM with Centos 7.
2- I stopped the PostgreSQL service: sudo systemctl stop postgresql-9.6
3- I renamed the /var/lib/pgsql/9.6/data folder to date data_old and
copied the old date folder
4- I gave permission in the folder date:
sudo chown postgres: postgres /var/lib/pgsql/9.6/data;
sudo chmod 700 /var/lib/pgsql/9.6/data
5 - I tried to start the service: sudo systemctl start postgresql-9.6
It is generating the following errors:

What do you see if you do the above, add -l to the systemctl command?

What does the system log show?
