> I found that one of rels in Relsub has parent Relsub as 'input' (Relsub and Project). Fortunately it was not selected to 'best', but Relsub print out first occurence of rel which match the trait, and unfortunately it's first one.
> Query is really simple, INSERT INTO BAR SELECT ID, NAME, ADDR FROM FOO WHERE ID > 3. I didn't see this when I directly uses Calcite logical.
> rels:
