compile error with GHC 7.2 & GHC 7.4

[hvr]

The .cabal file declares postgresql-simple to be compatible with base-4.4/base-4.5; this, however, doesn't seem to be the case (see below).

Please either restore compatibility or set a tigher lower bound in future releases, i.e. base >= 4.6 (I've already revised the .cabal file on Hackage as this was caused transitive failures for other packages depending on postgresql-simple: https://hackage.haskell.org/package/postgresql-simple-0.5.2.0/revisions/)

With base-4.4:
