I have an env running a changed data_directory fine in a devel machine
PG 9.4 using Fedora23.
Now, I have a server machine with CentOS where I downloaded the RPMs

https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-6-x86_64/pgdg-centos96-9.6-3.noarch.rpm.
All the configs run fine if I doesn't change the default data_directory.
But I need to use the path /sistemas/sat4/bdpg.

I did these commands:

mkdir /sistemas/sat4/bdpg
chown postgres /sistemas/sat4/bdpg
chmod 700 /sistemas/sat4/bdpg
su - postgres
/usr/pgsql-9.6/bin/initdb -D /sistemas/sat4/bdpg
exit

Then, I changed data_directory to /sistemas/sat4/bdpg and tried to

Changed data_directory where?

restart PG:
service postgresql-9.6 restart
STOP => OK
START => FAILED

I disabled se_linux.
The file /var/lib/pgsql/9.6/pgstartup.log just said to see future output
in pg_log.
The file data/pg_log/postgresql-Mon.log doesn't say anything about errors.

The strange is that startup arises a FAILED message, but the process
"/usr/pgsql-9.6/bin/postmaster -D /var/lib/pgsql/9.6/data" is running

So /var/lib/pgsql/9.6/data is where the original install is?

Best guess is that some script is starting the original install and when you go to start your custom location it fails because the new cluster is trying to use the port(5432 I am assuming) as the original cluster.

Have you tried giving the new cluster a different port number, say 5442, and the starting it?


(and the children logger/checkpointer/etc). But I don't get to connect
using pgAdmin3. Then, I have to kill manually postmaster (because
service script doesn't understand postmaster.pid in the new data dir),
comment data_directory to use default place, start and connect to
pgAdmin3. Then, start/stop/start/etc run fine lookup for postmaster.pid
in /var/lib/pgsql/9.6/data.

So you either need to change the start script to point to the new cluster or create a new one for it.
