postgresql-13-wal2json - 2.3-2+b1 main

wal2json is an output plugin for PostgreSQL's logical decoding. The plugin has
access to tuples produced by INSERT and UPDATE. Also, UPDATE/DELETE old row
versions can be accessed depending on the configured replica identity. Changes
can be consumed using the streaming protocol (logical replication slots) or by
a special SQL API.
.
The wal2json output plugin produces a JSON object per transaction. All of the
new/old tuples are available in the JSON object. Also, there are options to
include properties such as transaction timestamp, schema-qualified, data
types, and transaction ids.
