Postgres - 'ON CONFLICT DO NOTHING RETURNING id' statement

[vlauciani]

I'm using Postgres and I need to submit a query like:

insert into mytable (field1, field2) values (value1, value2) ON CONFLICT DO NOTHING RETURNING id

I tried to use insertOrIgnore() method but It build the query with only ON CONFLICT DO NOTHING; I tried to use insertGetId() method but It build the query with only RETURNING id.

Is there a way to "chain" the two methods?

I also tried to build a raw insert:

DB::insert('insert into mytable (field1, field2) values (?, ?) ON CONFLICT DO NOTHING returning "id"', [
                $value1,
                $value2
            ]);

but It doesn't return the id when the record is missing; It returns only true or false.

---

Could It be possibile to implement a new method like:

    public function compileInsertOrIgnoreAndGetId(Builder $query, $values, $sequence)
    {
        return $this->compileInsert($query, $values).' on conflict do nothing returning '.$this->wrap($sequence ?: 'id');
    }
