Yes, good catch. This is a bug. I will note that at least in 15 and
likely before, pgBufferUsage.local_blks_written is incremented for
local buffers but pgBufferUsage.blk_write_time is only added to for
shared buffers (in FlushBuffer()). I think it makes sense to propose a
bug fix to stable branches counting blk_write_time for local buffers
as well.
