I don't see logs mentioned. I agree with most those applications but would keep my OLAP stuff (metrics, logs, traces) in a separate store like VictoriaMetrics, both for capacity and read activity.

pg_timescale can take you pretty far for metrics and would be Good Enough for almost all users. Totally agree on raw, high-volume logs though.

Yeah I have logs in Sentry, which also uses Postgresql.
