Then, I changed data_directory to /sistemas/sat4/bdpg and tried to 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 (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.
What is the value of data_directory in postgresql.conf ?
Is there anything in /var/log/postgresql/{log_filename} ... where {log_file} is the value set in postgresql.conf ?
