doc: Improve description of wal_receiver_status_interval
This parameter description was previously confusing, telling that avalue of 0 disabled completely status updates. This is not true asthere are cases where an update is sent while ignoring this parametervalue. The documentation is improved to outline the difference oftreatment for scheduled status messages and when these are forced.Reported-by: Dmitriy KuzminAuthor: Michael PaquierReviewed-by: Euler TaveiraDiscussion:https://postgr.es/m/161346024420.3455.1345266601055047937@wrigleys.postgresql.org
