示例1: safeGetLag
/**
* Get the lag in seconds for a given connection, or zero if this load
* balancer does not have replication enabled.
*
* This should be used in preference to Database::getLag() in cases where
* replication may not be in use, since there is no way to determine if
* replication is in use at the connection level without running
* potentially restricted queries such as SHOW SLAVE STATUS. Using this
* function instead of Database::getLag() avoids a fatal error in this
* case on many installations.
*
* @param IDatabase $conn
* @return int|bool Returns false on error
