Hi,
In the stats_ext regression test, there is a function
check_estimated_rows that returns actual rows as an integer. Currently,
none of the test cases produce a non-zero fractional part in actual rows.
The question is: should this function be modified to return a fractional
number instead of an integer?
Personally, I don’t see much value in doing so, because the purpose of
the test is to compare the estimated row count with the actual number of
rows. It is also unlikely that there will be test cases where loops > 1,
and the presence of a fractional part does not change the essence of the
test.
What do you think?
