Specifying backend=pgmoon now required?

[cycomachead]

Sometime with 1.13.x or 1.14, it seems I now need to specify backend = "pgmoon" when using a postgres connection. In development, I think thing were fine but in our staging environment we saw the following error.

The update successfully completed, but it seems like the error was in reporting the success/failure of the action.

Anyway, I'd just like to confirm if this is the expected behavior or if there's some other configuration I should be making?

Oh, I made too many changes at once! It seems like the server didn't have the most recent pgmoon installed, which makes sense.

All is well. :)
