POSTGRES_TOPOLOGY_SETTINGS

POSTGRES_TOPOLOGY_SETTINGS Dynamic Config

Dynamic config that controls topology settings of service's PostgreSQL components.

Dictionary keys can be either the service component name (not database name!) or __default__. The latter configuration is applied for every non-matching PostgreSQL component of the service.

Take note that it overrides the static configuration values of the service!
