It's a known problem that 'join in many-to-many' doesn't fill in certain
external fields. Like the table name and column names. Well, whether this
is a problem or just the design of it is a matter of opinion. But it's
known that you have to go and fill in the column names and table name
yourself after using 'join in many-to-many'. Once you've done this, it
should work fine.
Since it's easy to get some of the settings wrong for a flattened
many-to-many in your model, it is reccomended to use 'join in many to many'
and then fill in the missing fields, rather than doing it by hand. Although
doing it by hand works fine too of course, as long as you get everything
right.

I used the "join in many-to-many" button in EOModeler to create a join table.
When I then generated the SQL to create the database.
That SQL lacked the commands needed to create the join table.
However, if I created the join table then set up the relationships myself
the generated SQL was correct.
I'm using PostgreSQL and its plugin.
Is this a known problem? Is it a PostgreSQL-only problem?
