ANNOUNCE: Hasql: A minimalistic general high level API for relational databases

[Nikita Volkov]

This library takes a mission of upgrading the experience of dealing with
relational databases in Haskell. It’s robust, it’s API is very concise, yet
it’s packed with powerful features like the following:

   -

   An abstraction over transactions, which provides an automated resolution
   of conflicts. The API ensures that you’re only able to perform a specific
   set of actions in the transaction context, which allows Hasql to safely
   resolve conflicting transactions by automatically retrying them. This is
   much inspired by STM and ST.
    -

   Support for cursors. Allows to fetch virtually limitless result sets in
   a constant memory using streaming.
    -

   Employment of prepared statements. Every statement you emit gets
   prepared and cached. This raises the performance of the backend.
    -

   Automated management of resources related to connections, transactions
   and cursors.
    -

   A built-in connections pool.
    -

   Type-level generation of templates. You just can’t write a statement
   with an incorrect number of placeholders.
    -

   Mapping to any types actually supported by the backend.
