I've heard that Debezium users, a tool for change data capture, can use pgoutput as the logical decoding plugin. I also know users, including some of my colleagues, who use pgoutput with pg_recvlogical to capture messages inserted via pg_logical_emit_message(). So I think making the pgoutput documentation easier to find would be helpful for those users. Regards, -- Fujii Masao
