Are you saying you'd want to set the threshold to *more* than the window
height? Why?
My impression is that the problem is not with the threshold as such,
it's that psql is not terribly careful about determining how many lines
it will put out (ie, the value being compared to the threshold isn't
100% reliable). If that's correct, then a hand-set threshold isn't
really going to make you happier, and what's needed is some hard work
on improving the quality of the lines-to-be-output estimates.
