IIRC, the EXECUTE command does not change FOUND --- leastwise it's not
listed as one of the plpgsql commands that do set FOUND.
Do you really need an EXECUTE? If so, maybe you could restructure this
using a FOR ... IN EXECUTE, or some such thing.

Well, that might work. Have you thought through the corner case
where the query does find a row but the field's value is null?
