Pgroll: zero-downtime, undoable, schema migrations for Postgres
Very cool! Congratulations to the authors on the release! I'm the author of a similar (zero-downtime migration) tool for PG called QuantumDB[0]. It was the first (to my knowledge at least) tool to support foreign keys, by creating table copies (keeping those in sync using triggers), and exposing multiple schemas through a custom database driver. I never got to production-ready version unfortunately, but I'm happy this one did. I'm seeing a lot of familiar concepts, and it looks well thought out.

Building a faster hash table for high performance SQL joins
Looks like full keys are always compared if hash codes test equal, which is what I'd expect. For example: https://github.com/questdb/questdb/blob/master/core/src/main...

K3s Traefik Ingress - configured for your homelab!
But of course, I want to run a QuestDB instance on my node, which uses two additional TCP ports for Influx Line Protocol (ILP) and Pgwire communication with the database. So how can I expose these extra ports on my node and route traffic to the QuestDB container running inside of k3s?
