Is there any way to define many to many relationship?

What I have only found is defining foreign key relations to another table. I can not managed to fine the many to many relationship definition. So do I manually need to create a third table with table_1_id and table_2_id column define their foreign key and go after so on?

Yup, that would be the way @dgvai.
Haven't tried this but I think after you do that, you can query it with postgrest resource embedding without specifying the intermediate join table.
