* + <structfield>sent_bytes</structfield><type>bigint</type> + </para> + <para> + Amount of transaction changes sent downstream for this slot by the + output plugin after applying output plugin filters, if any, and + converting it into the output plugin format. BTW, this also contains changes from pgoutput_message() which could be non-transactional. So, saying transaction changes may not be appropriate. * We also send keep_alive kind of messages via wal_sender, those are not counted in sent_bytes. If we don't want to include those then does that need a mention? -- With Regards, Amit Kapila.
