+- The database pooler is now dynamic. New connections are opened when needed and closed after a configurable period of time. This can be configured through `connections-pooler-max-size` (default 0, unlimited), `connections-pooler-min-size` (default 0), and `connections-pooler-idle-timeout` (default 600 seconds). The old configuration `connections-pooler-size` has been dropped.
