Is it possible to find the number of disk IOs performed for a query?  EXPLA=
IN ANALYZE looks like it shows number of sequential rows scanned, but not n=
umber of IOs.=20=20

My database is on an NVMe SSD, and am trying to cut microseconds of disk IO=
 per query by possibly denormalizing.

Thank you,

-bobby
