I am playing with pgoutput and logical replication. With wal2json, I could
capture the old values before the row was updated. I am unable to figure
out how to do that with pgoutput. Does pgoutput even support this?
Relevant info from wal2json:
> Also, UPDATE/DELETE old row versions can be accessed depending on the
configured replica identity
> All of the new/old tuples are available in the JSON object.
