If you [edit go.mod](https://github.com/dpooley/outflux/commit/7c332e8a25466ca19f48a24274b60b876d24b53b) and build `outflux` with pgx v3.4.0+ then `scram-sha-256` authentication is [supported](https://github.com/jackc/pgx/commit/5044e8473ad948114b6cb63f6f30f94fc7834667), and appears to work OK (from my limited testing).
