I loved this one! I love how PG allows the entire record to be easily encoded and stored. We implemented an audit feature like this in Oracle. It was way too much code. We stored the OLD and NEW record. When I saw how easy it was for a single table in PG... I started falling in love... For us, the table, and the timestamp was always attached. To Answer the question: "How do you show this to the Manager" (the record changes. Assuming you stored the table_name, table_id columns with it. Then you would create a visible link that pointed to that record if there was an updated record in existence. And if it is a deleted recorded you will either need to merge it into the results, or show them NEAR the messages of the rough similar timestamp. You don't have to show them. Just show that they exist, with an easy way to get to them. FWIW, Day 1 in training. We showed users that all of their edits were stored. And Deletes were Stored as well. we only had to recover a couple of times.

i always do add a reserve "flag column" to my tables, usually type int, no matter what the table serves for, it comes very handy, gives a flexibility that glue it any other table, service or logic etc.
