So I managed to build something that I’m quite satisfied of (although still much room for improvement), Ezpostgresql (name shamelessly inspired by Ezjsonm, as I am bad at giving names):
At this point it’s only compatible with Lwt since I’m not sure how to make one that can work with both Async and Lwt. You can see the examples on the README for more info. And yes, it also supports connection pooling out of the box via Lwt_pool. Do note it’s still WIP and by no means stable yet!
