+ In logical replication walsender, fix failure to send feedback

+ </para>
+
+ <para>
+ This is a relatively minor problem when using built-in logical
+ replication, because the built-in walreceiver will send a feedback
+ reply (which clears the incorrect state) fairly frequently anyway.
+ But with some other replication systems, such
+ as <application>pglogical</application>, it causes significant

+ Fix <application>pg_recvlogical</application> to drain pending

+ </para>
+
+ <para>
+ Without this, the replication sender might detect a send failure and
+ exit without making the expected final update to the replication
+ slot's LSN position. That led to re-transmitting data after the
+ next connection. It was also possible to miss error messages sent
+ after the last data that <application>pg_recvlogical</application>
+ wants to consume.
