32895	Incorrectly disallowing negative integer for window range end	henribru	nobody	"In `window_frame_end` Django is currently enforcing that the `end` argument of `ValueRange` and `RowRange` can't be a negative integer. However, according to the Postgres documentation, ""value PRECEDING"" is allowed for ""frame_end"", so a negative integer is equally valid for `end` as it is for `start`.
