Refer to supplementary content APPENDIX-B for documentation on installing pgaudit. With pgaudit installed, the following configurations can be made: $ sudo su - postgres $ vi ${PGDATA?}/postgresql.conf Add the following parameters (or edit existing parameters): pgaudit.log_catalog = 'on' pgaudit.log='ddl, role, read, write' As the system administrator, reload the server with the new configuration: $ sudo systemctl reload postgresql-${PGVER?}
