Hi Jürgen,
You are not doing anything wrong, that is how it is supposed to work. The GlobalID for all objects in the hierarchy is generated from the top most (abstract in your case) Entity name and the primary key. That implies that the primary key need to be unique across all of the tables in the hierarchy, not just in each table. To ensure this, EOF only generated PKs from the sequence in the top most entity/table.
I am not sure why it is not generating a table for that entity, I don't use Postgres much. Did you define the table name and the column names etc in the model?
