My team and I had the exact use case.. here is what we came up with: https://github.com/chop-dbhi/diff-table#diff-table https://github.com/chop-dbhi/diff-table#diff-table Supports delimited files and Postgres tables. Outputs a large JSON-based summary of record diffs or it emits an event stream as changes are found (and thus does not hold the summary in memory).
