You should just give it a shot in 10-15 min and see how it looks with ClickHouse. We made it that simple with ClickPipes :). Don’t intend to sell here, but it is as simple as signing up for trial on ClickHouse Cloud and clicking a few buttons and start seeing PG data getting synced.

In regards to footguns with replication, totally understand you being cautious. Last 2 years at PeerDB/ClickPipes was laser focused on just Postgres CDC to provide a dead simple yet highly reliable experience. The product has 100s of features, addresses 100s of footguns and actively being enhanced. Sharing some customers using this production https://clickhouse.com/blog/postgres-cdc-year-in-review-2025... You should give it a shot to see how easy it is. :)

In regards to sample apication, here is one, https://github.com/ClickHouse/HouseClick It showcases PG + CH stack. We just merged a PR to integrate pg_clickhouse too. The good news is that, there is a blog planned in a couple of weeks which showcases a tightly integrated experience PG +CH with CDC and pg_clickhouse, all in OSS. It will have docker-compose too. Your question adds up to what we are thinking next, I couldn’t resist myself to reveal it. ;) :)

Nice! Looking forward to reading it!
