I got this exception trying execute (persist) the below code snippets:

Postgres tables are:
1- users (id, ...)
2- user_roles(user_id, role)

Because you are using @GeneratedValue()

It will look for how the database that you are using generates ids. For MySql or HSQSL, there are increment fields that automatically increment. In Postgres or Oracle, they use sequence tables. Since you didn't specify a sequence table name, it will look for a sequence table named hibernate_sequence and use it for default. So you probably don't have such a sequence table in your database and now you get that error.

Either add a hibernate_sequence or
your own sequence table and use the annotations to name your sequence table that you have.

Hope that helps
