Hi Hamish,
Features in process-leksah have been merged into process. For newer
versions of GHC leksah-server just depends on process.

announced, right? (The latest release versions still seem to depend on
process-leksah.) In

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:
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.

AFAIK, persistent's PostgreSQL support does depend on libpq via
postgresql-libpq.

I think acid-state (http://hackage.haskell.org/package/acid-state) might do
what you want, at least in broad strokes. It uses a durable transaction log
to store query and update events.
As far as I know, the interface to the library doesn't expose an
undo/rollback function, so you'd have a bit of
Hi Ben,
Thanks for the reply.
I am planning on using Persistent which can work without template haskell,
though I am planning on using the TH on my workstation to create the boiler
code parts of the database setup.
The part that I'm having trouble with is collecting the composed functions.
