Hello
create table event_types ( id number constraint event_types_id_pk primary key ) ;
and
create table event_types ( id number generated by default on null as identity ) ;

unfortunately return empty array

those could also be written like this

create table event_types ( id number generated by default on null as identity constraint event_types_id_pk primary key ) ;

python 3.10.12 , v0.30.0
