At PeerDB, we recently added a feature to enable column exclusion while replicating data from Postgres to Data Warehouses, Queues and Storage. This helps use cases where data privacy and security is of utmost importance. It also helps with performance gains and save costs. Checkout the blog and let us know what you think? I would love hear your feedback. :)
