Dependency Error when installing v0.3.0 (outdated "postgrex")

[dalerka]

Thanks for working on this lib. Could you please update the deps requirements? Otherwise, I'm getting this error (with phoenix 1.4.0):

 $ mix deps.get
Resolving Hex dependencies...
Failed to use "postgrex" because
  ecto_sql (version 3.0.3) requires ~> 0.14.0
  ecto_trail (version 0.3.0) requires ~> 0.13.2
  mix.lock specifies 0.14

EDIT: tried to override as {:postgrex, "~> 0.14.1", override: true} and found another conflict:

 $ mix deps.get
Resolving Hex dependencies...
Failed to use "ecto" (version 3.0.5) because
  ecto_sql (version 3.0.3) requires ~> 3.0.4
  ecto_trail (version 0.3.0) requires ~> 2.1
  phoenix_ecto (version 4.0.0) requires ~> 3.0
  mix.lock specifies 3.0.5

I'm all up to bump deps, PR would be welcome :).
