Here are the settings in the postgresql.conf file: I remember turning on logging to troubleshoot a performance issue log_destination = 'stderr' logging_collector = on log_directory = 'pg_log' #log_filename = 'postgresql-%a.log' log_truncate_on_rotation=on log_rotation_age = 1d log_rotation_size = 0 I installed postges from an rpm file (pgdg-redhat92-9.2-7.noarch.rpm) using yum install.

Thank you! I deleted data directory again and then ran initdb. This time service started successfully.

I tried su - postgres and then from the bash shell i tried to run these commands (tried one at a time) but it said address in use there are no processes running on 5432. How can I start postgres service? See if there are processes running for user postgres that look like database processes and kill them. Then try again. What exactly is the error message?

Re: [ADMIN] accidentally deleted data directory
If pgstartup.log is empty that points at an issue with the configuration file. From memory, when you do an initdb it recreates the configuration files in the /var/lib/pg... directory. I would look at the main control file and the pg_hba.conf and try to start the database passing it the name of the main conf file as a parameter (as well as the database directory).
