hello,

there is something I seem missing in explain analyze buffers results when
track_io_timing is on:

this is the first lines of an explain: (the request is of no interest, such
a result is quite frequent)

Nested Loop Left Join (cost=941400.77..966327.57 rows=3 width=653) (actual
time=52655.694..62533.811 rows=346 loops=1)
Buffers: shared hit=10068265 read=396705 dirtied=1858 written=218, temp
read=429687 written=115187
I/O Timings: read=79368.246 write=11.486

So, the total execution time is 52655 ms ok
and the total time for i/o is...79368 ms

how ???

thanks
