I actually did from a file, but with the \i command.

The data type serial is a standard data type, which is also included in
PostgreSQL ;-). M$Access calls it 'Autonumber' and is simply an integer (I
think it is most common to be an int4) that is automatically incremented for
each insert. I think that it is implemented in PostgreSQL using a sequenser.
I tried to change the name of the serial field: globalafvigelse -> id,
and then it works. I think it is because postgresql automatically creates a
sequence called <table name>_<field name>_seq, which is limited in size.
