It is pointed out in https://www.pgpool.net/mantisbt/view.php?id=806
that there are log entries in the log file:
LOG: pool_pending_message_set_flush_request: msg: Parse
The messages were for debugging and the log level should have been a
DEBUG*. So I changed the log level from LOG to DEBUG5.
{
POOL_PENDING_MESSAGE *msg = (POOL_PENDING_MESSAGE *) lfirst(msg_item);
msg->flush_pending = true;
- ereport(LOG,
+ ereport(DEBUG5,
(errmsg("pool_pending_message_set_flush_request: msg: %s",
pool_pending_message_type_to_string(msg->type))));
}
