Guess I'll work around my migration problems with placeholder default values. I tried another approach at the same time. I tried to alter the tables that had changed between versions of the sql structure. The problem with this is that postgres is unable to add a field to a table with a NOT NULL constraint. You can add a NOT NULL constraint to the field afterwards but now all records in the table have a NULL value in the field. So you wont be able to do that until you change all the values. No default value was specified for the new field. As with the other approach this might also work if I enter some default values.
