Proposal: strict insert types

[Antony1060]

insertInto currently applies Partial to the table type. I suggest we don't make it Partial anymore. In pretty much every use case, the developers will type their tables appropriately and inserting data that is not complete should not be possible. Furthermore, selecting data after a partial insert is going to be typed wrong.

Partial inserts can still be done with update so the options are still there.
