Well, I answered my own question. Unlike UNIX, specifying a library without the leading "lib" causes the library to not be found. Not sure if that's a GHC linking problem or what. Changing the library requirement to "libpq" in the .cabal file did the trick tho.
This seems to be a bit different from what I discovered when cabalising Takusen. ghc uses gnu ld, which seems to be smart enough to know that -lpq means "find libpq.dll or pq.dll". ghci's linker/loader isn't so slick. If you say -lpq to ghci, it looks for pq.dll only. So I just copied libpq.dll to pq.dll, so that they both exist. You're using runghc, so I guess that must use ghci, or something equivalent. You may find, now that you've changed the cabal entry to libpq, that you can no longer build with ghc (the compiler). But my memory of this is hazy. I think it's better to stick with "pq" in the cabal file (and copy libpq.dll to pq.dll), because this works for Unix systems too.
