It doesn't give you the wal_buffers value. It only says "hey, I needed more buffers so I write those dirty ones". It doesn't say how many. I would like to have something that says "hey, you have 1000 buffers available and you are using 100 buffers (10%)". This new statistic is only useful for decreasing the WALWriteLock contention.
