A while ago I saw a mention on the mailing list of someone interested in making Calcite speak Postgres' wire protocol, so all existing tools/client libraries could interface with it.
I couldn't find anything on the internet for this -- either for Calcite,or surprisingly even a JVM toolkit for building wire protocol services (empty interfaces) Spent the last few weekends hacking on this, just today got a prototype to a point where I can query Calcite from psql Thought I'd share here in case others are interested, here's a video demo and repo: https://twitter.com/GavinRayDev/status/1523048629883514881 https://github.com/GavinRay97/PgProtoKt
