Did you know that Postgres that lets you write data that you can’t query? Events that will show up in the write-ahead log (WAL) of the database but not in any table.

Gunnar Morling, senior staff engineer at Decodable and world expert on change data capture, walks us through data capture basics, this not-new but little-known feature, and dives into three key use cases (my favorite is the audit log) plus a bonus example that goes deeper into Postgres internals.

We discuss these blogs and examples in the video:
