Dan,
Yes, the exact query looks like this:
with gsrange(f, t) as (values(1, 10))
select if(value == f, null, value-1) as rowvalue_1,
value as rowvalue_2,
if(value == t, null, value+1) as rowvalue_3,
if(value == f or value == t,
(if(value == f, 0, value-1) + value +

I see that there is a new create function to create the window functions which

Furthermore, I've found another example of a window function returning
incorrect results.
Using the above "sample" table and sample data, the following query
produces the wrong results.

Thanks. Worth testing just in case something weird happened. But it didn't.
I leave it up to the experts.

Wording looks great, thanks Dan.
FWIW I believe the same docs issue applies to the FTS5 module.
Docs are hard, I often find myself re-reading paragraphs and then figuring
out that I'm just a big dummy and didn't 'get it' the first time.
The FTS docs are actually pretty great, they introduce some
