Fix Recommendation

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

First edit the postgresql.conf file as the database administrator (shown here as "postgres"):

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

Extra parameters can be added to the setting log_line_prefix to log application related information:

# %a = application name
# %u = user name
# %d = database name
# %r = remote host and port
# %p = process ID
# %m = timestamp with milliseconds
# %i = command tag
# %s = session startup
# %e = SQL state

For example:

log_line_prefix = '< %m %a %u %d %r %p %i %e %s>'

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

$ sudo systemctl reload postgresql-${PGVER?}

Check Contents

First, as the database administrator (shown here as "postgres"), check the current log_line_prefix setting by running the following SQL:

$ sudo su - postgres
$ psql -c "SHOW log_line_prefix"

If log_line_prefix does not contain "%m %u %d %s", this is a finding.
