Well, you'll get a page worth of data before your pager blocks it,
and then you can continue, or not, for relatively little cost.
I can't see that fetching a fixed number of rows is more useful
than that.

doesn't realize that it could be applied to a "TABLE foo" query.
That seems like it might be worth fixing.
