Configuration

The parameters listed in the table represent the specific configuration settings that we customize from the default configuration provided by PostgreSQL. These parameters are tailored to suit our platform’s requirements and are carefully selected to optimize performance and reliability.

Note: Parameters marked with an asterisk (*) are dynamically calculated based on available compute resources, allowing for seamless vertical scaling.

You can change the parameters listed in the table yourself in Cloudhub.

Note on activating extensions:

  • Extensions marked Self-service can be activated directly in your database with CREATE EXTENSION <name>;.
  • Extensions marked Via ticket are activated for you by our support team. Please submit a support ticket.
  • postgis_raster, postgis_sfcgal, postgis_topology and postgis_tiger_geocoder require postgis. postgis_tiger_geocoder additionally requires fuzzystrmatch.
  • plpgsql is installed by default in every database.

If you need a parameter that is not listed or want an extension activated, please submit a support ticket.
