Comment(by mightybyte):
I played around with this a little more. First of all, I did some general
work to the code in the snaplet-postgresql-simple code and the GHC panic
still happens in the most recent code I've committed.
Secondly, the panic goes away and the app builds cleanly if I remove the
existential on line 31 of example/Site.hs and use "App" instead of the
type variable on line 34 (https://github.com/mightybyte/snaplet-
postgresql-simple/blob/master/example/Site.hs).
With this in mind, I played around a little bit trying to create a minimal
test case that demonstrates the problem, but thus far I've been
unsuccessful.
