I went with db_postgres as well. Unfortunately, it is not async. I did consider treeform's pg, but unfortunately i did not get any reply from him on my question so decided not to go with it for the TE benchmarks. I think the lowest hanging fruit for db drivers would be to just wrap libpq, the default PG driver. Given Nim's c interop, that should be easy. I was planning to do that, but then life happened and I had to skip that project. I would say, that if you are trying to create a very involved framework, you should look to solve this problem. Otherwise the current perf of db_postgres can be a big deterrent to a lot of potential users.
