I’m locating the project and the current Postgres→ClickHouse copy flow first, then I’ll patch the import so reruns stay idempotent and verify it against the local setup.

I need to copy our orders data from Postgres to ClickHouse for analytics. The problem is if I run the copy again it creates duplicates.

Can you set it up so the data gets into ClickHouse without duplicates if I run it again?
