AFAIK, persistent's PostgreSQL support does depend on libpq via postgresql-libpq. On Wed, Jan 9, 2013 at 12:39 PM, Alexander Alexeev wrote:

Try Persistent package. It doesn't depends on libpq and has many useful features (see http://www.yesodweb.com/book/persistent for details)

Tricky. For what it's worth, if you can't figure this out in the end, you could perhaps use my pgsql-simple which is implemented in pure haskell: https://github.com/chrisdone/pgsql-simple It's been in use on hpaste.org for about 2 years.

Hello Community,

I have a problem installing the HaskellDB-HDBC-PostgreSQL package with cabal. I'm using Haskell Platform in Windows and I tried to install this package, but there was the error "could not find pq library". So I tried to install libpq wich includes pq but there was another error: "this package needs a unix installation". Is there any way to install pq on Windows or get the HaskellDB-HDBC-PostgreSQL in another way?

Thanks for your advice

Johannes Reiher
