**Table 1** PG_COMM_DELAY columns
Name	Type	Description
node_name	text	Node name
remote_name	text	Name of the node with the maximum latency in connecting to the peer end.
remote_host	text	IP address of the peer.
stream_num	integer	Number of logical stream connections used by the current physical connection.
min_delay	integer	Minimum delay of the current physical connection. The unit is microsecond.
average	integer	Average delay of the current physical connection. The unit is microsecond.
max_delay	integer	Maximum delay of the current physical connection. The unit is microsecond. NOTE: If its value is -1, the latency detection has timed out. In this case, re-establish the connection between nodes and then perform the query.
