[ANN] hpgsql, a pure Haskell PostgreSQL driver (no libpq)

Nice, I wrote a very naive pure Haskell implementation (GitHub - chrisdone-archive/pgsql-simple: A mid-level client library for the PostgreSQL database, intended to be fast and easy to use. · GitHub) back in the day before I knew anything about writing performant Haskell. I’d been recently perusing the protocol documentation again, thinking I’d do a fresh ground up implementation for fun, try for zero-allocation message handling I’d possible, and really take advantage of the implementation being in Haskell. Nice to see someone take a swing at it! I’m curious, what’s the thread safety situation?
