All resources of one cluster should belong to one application label, not an extra application. On the other hand, there should not be two pods queryable with
application: spilo, spilo-role: master. Therefore, the role identifier for pooler pods must be changed, too.As this is a breaking change, we introduce new config options to be able to continue using the old way of labelling, meaning:
connection_pooler_labels: application:db-connection-poolerconnection_pooler_role_label: spilo-roleThe new defaults used for these two config options are:
connection_pooler_labels: component:db-connection-poolerconnection_pooler_role_label: pooler-role
