TimescaleDB looks great. I'm interested in using it but I'm concerned about the upgrade path across major PostgreSQL versions. Logical replication is a big help when upgrading PostgreSQL across major versions while minimizing downtime. As far as I understand it, TimescaleDB doesn't support logical replication yet. Major version upgrades with TimescaleDB is obviously a solvable problem but it probably means we'll have a more complicated upgrade path. Upgrading via logical replication is just so nice.
