There is also Debezium. I think there are other CDC (change data capture) systems built around PG logical replication, which is itself built around logical decoding of the WAL. It's a fairly obvious idea, though I wish:

- PG did logical logging natively instead of via WAL decoding

- PG logged commit records in the WAL so that any code replaying transactions from following the logical replication stream can isolate each transaction's changes and serialize everything correctly
