Wrong cardinality estimate for select * FROM KS2 x WHERE ANY v IN uarr_i satisfies v = 74505 END type of queries

select * FROM KS2 x WHERE ANY v IN uarr_i satisfies v = 74505 END

uarr_i is a uniformly randomly distributed array with array length uniformly varying between 0 and 100.

Hence estimating cardinality of above query should not be difficult to estimate.
