- Forgetting to include a primary key on a non-autoincrement table
- Compound primary keys
- Rowid only tables with and without rowid specified

Three options:
1. Ignore that and document it

3. Change the name of `""inserted""` to something else

I'm torn on this one. It's something you can do with direct database access, but it's something I very rarely want to do.
I'm inclined to disallow it and say that if you want that you can get it using a writable canned query instead.
Likewise, I'm not going to provide a way to set the `rowid` explicitly on a freshly inserted row.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1428630253,
