RealtimeSystemPayload
@Serializable
Payload of a system event emitted by the server.
Most notably, when a channel is created with BroadcastJoinConfig.replicationReady: true, the server sends one of these once the Postgres replication connection is ready (status: 'ok') or fails to become ready in time (status: 'error').
Parameters
extension
The extension that produced the message, e.g. 'system' or 'postgres_changes'.
status
'ok' on success, 'error' on failure.
message
Human-readable description, e.g. 'Replication connection established'.
channel
The channel (sub)topic the message refers to.
