Create table without PRIMARY KEY

[IevgeniiB]

Hello!

I'm trying to use mosql, but always run into this issue: I have such config file:

test:
    restaurants:
        :columns:
            - name: TEXT
            - restaurant_id: TEXT
        :meta:
            :table: restaurants
            :extra_props: true

I have no primary key here. But mosql generates such query for table creation:

CREATE TABLE "restaurants" ("name" TEXT, "restaurant_id" TEXT, "_extra_props" TEXT, PRIMARY KEY (NULL))

Seems that PRIMARY KEY (NULL) has no sense. Maybe I'm doing something wrong? Is there some way to specify primary key if needed?

If someone will experience such issue - don't forget to import _id field as well
