Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging. 

If logging is enabled the following configurations must be made to log connections, date/time, username, and session identifier. 
First, as the database administrator (shown here as "postgres"), edit postgresql.conf: 

$ sudo su - postgres 
$ vi ${PGDATA?}/postgresql.conf 

Edit the following parameters as such: 

log_connections = on 
log_line_prefix = '< %m %u %d %c: >'  

Where: 
* %m is the time and date 
* %u is the username 
* %d is the database 
* %c is the session ID for the connection 

Now, as the system administrator, reload the server with the new configuration: 

# SYSTEMD SERVER ONLY 
$ sudo systemctl reload postgresql-${PGVER?} 

# INITD SERVER ONLY 
$ sudo service postgresql-${PGVER?} reload
