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

To ensure logging is enabled, see the instructions in the supplementary content APPENDIX-C.

If logging is enabled the following configurations must be made to log connections, date/time, username, and session identifier.
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

As the system administrator, reload the server with the new configuration:

$ sudo systemctl reload postgresql-${PGVER?}

PostgreSQL must generate audit records when successful logons or connections occur.
