I think the best way to test this would be to put PgBouncer or a similar proxy in front of a busy production database, and mirror queries to both traditional Postgres and the Rust one at the same time. Then you can compare output and performance under real load. After running it for a while, you could diff the tables one to one against the normal Postgres instance.

Can you control the timing of queries across two db instances well enough to expect the tables to be identical?

Good question, I guess you can run two identical Postgress instances and check if they have a diff
