SQLite with insert returning not working as in PostgreSQL

Testing the recently welcome added "returning" clause for inserts with this query that does work in PostgreSQL but doesn't in SQLite: ==== create table test(id integer primary key, data text); with insdata as (insert into test(data) values('one') returning id) select * from insdata; ==== Is this a limitation of the current implementation ?

Except that thread somehow couldn't get the same SQL to work in PostgreSQL.
While here, Domingo claims this is working fine in PostgreSQL, and SQLite
does strive for compatibility in that area. Thus that matters.
But indeed, as long as divergence and limitations are clearly documented,
it's completely OK for Richard to reduce the surface area of this new feature,
which is also a welcome addition from my end.
If Richard could actually explain how it works, and more precisely how that
magic trigger allows gaining
RETURNING support, I'd be glad. I know he's
a super busy person, but I really wish for more deep dives from him on SQLite
subjects, like SQLite internals. He is such an interesting and amazing mind.
