> All table functions cause errors in queries containing RIGHT or FULL JOINs. For example, such query:
> {code:sql}
> select * from views.v x1 right join table(select x1.b a) x2 on x1.a=x2.a ;;
> {code}
> causes such error:
> {code:noformat}

> The behavior is expected. Lateral is expected to work left to right - thus only with inner/left joins. The error message should be improved. On pgsql it is "The combining JOIN type must be INNER or LEFT for a LATERAL reference".
