Could anyone help me please?
We can start by assuming that Django itself isn't broken at the basic level. Many-to-many fields work and the feature described in that documentation works. So the error is caused by something you have done -- in your code or in the way you've created the models. Since the error is PostgreSQL reporting that the database schema doesn't seem to be set up properly (Django will never explicitly refer to a sequence name except when creating tables), it sounds like the latter. The point is, the problem is caused by something in the code you haven't shown us and is dependent upon your models and what you are doing to trigger the problem. So please provide at least some information about that. Some kind of context for what you did to cause this. Given what I wrote in the previous paragraph, how did you create the intermediate table? Did you make alterations to an existing table and then not manually alter the database? Are you modeling an existing database table? What version of Django are you using? Which database backend?
