I'm getting schema errors, specifically:
* relatedcontent.nid is part of the primary key but is not specified to be 'not null'.
* relatedcontent.vid is part of the primary key but is not specified to be 'not null'.
* relatedcontent.include_nid is part of the primary key but is not specified to be 'not null'.
* relatedcontent_view.type is part of the primary key but is not specified to be 'not null'.
* relatedcontent_view.vid is part of the primary key but is not specified to be 'not null'.

I can fix this in the table, (though I'm reticent to tinker) but why would I be having this issue to begin with?
