Sie sollten die Reihenfolge in der Datenbank vor dem Einfügen mit automatisch generierten Werten zurücksetzen. Es hängt stark von der Tabellen-DDL ab. Es gibt zwei Beispiele für das Autogen der am häufigsten verwendeten IDs:
/*
-- Be careful with these 3 lines if you already have such objects in the your DB
drop table if exists t1;
drop table if exists t2;
drop sequence if exists seq_t2_id;
*/
-- Using serial type for ID
create table t1 (t1_id serial, t1_name char varying);
insert into t1 (t1_id, t1_name) values (22, 'aaa');
select setval(pg_get_serial_sequence('t1', 't1_id'), (select max(t1_id) from t1)); -- Reset serial value
insert into t1 (t1_name) values ('bbb');
select * from t1;
-- Using sequence to generate IDs
create sequence seq_t2_id;
create table t2(t2_id bigint default nextval('seq_t2_id'), t2_name char varying);
insert into t2(t2_id, t2_name) values (22, 'aaa');
select setval('seq_t2_id', (select max(t2_id) from t2)); -- Update sequence
insert into t2 (t2_name) values ('bbb');
select * from t2;
