Wouldn't you also want to use this interface type elsewhere where a DB or Tx is required?

I don't have any (yet), I was just trying to say that it's not that special and one can use it anywhere else if they need to.

For me the last insert ID makes only sense for immediate subsequent processing – which just screams transaction. So I'd just allow Tx as parameter for now unless/until someone finds an actual use case with DB. (But then I'd:
- unexport the interface OR
- aggregate there all interfaces and non-interface methods both Tx and DB implement.)
