Yes, but remember that ANALYZE doesn't scan the whole table; it'll only
set the bit on rows it visits.
(I forget at the moment if it's guaranteed to set the bit on all rows
in each page it examines, or only on the rows it selects to sample.
But in any case it will not examine every page in the table.)
