Postgres synchronization solution P&L: -8 (≃ -8 HUR)

I want to take one set of data and synchronize it with another set where there could be changed to columns, new rows and deleted rows
YAML Project Produce

This is a challenging computer problem, data synchronization but I have an idea

I plan to use a inefficient rolling hash and sorting to solve the problem of synchronization. This is similar to rsync
