Compare your Configuration: 13
Select the version of Postgres that matches your configuration. Then, paste your configuration below to compare.
The custom config tool compares the contents of your postgresql.conf against the defaults for the selected version. Commented out parameters are discarded, just as they would be by Postgres. This query against pg_catalog.pg_settings prepares the settings as seen by the current session. This can be helpful to see exactly what configuration is active right now. It is also useful for using various DBaaS (Database as a Service) offerings, such as Amazon RDS, when access to the postgresql.conf file is not an option.
SELECT name || ' = ' || '''' || setting || '''' FROM pg_catalog.pg_settings;
