Well, Microsoft SQL Server has built-in Temporal Tables [1], which even take this one step further: they track all data changes, such that you can easily query them as if you were viewing them in the past. You can not only query deleted rows, but also the old versions of rows that have been updated.

(In my opinion, replicating this via a `validity tstzrange` column is also often a sane approach in PostgreSQL, although OP's blog post doesn't mention it.)
