-    if (!am_walsender)
+    if (!am_walsender || am_db_walsender)
         appendStringInfo(&ps_data, "%s ", port->database_name);

Can the appendStringInfo be just unconditional? That is more readable
IMO. We want the database_name to be appended whenever it isn't null.
The only case we expect database_name to be null is for walsenders
serving streaming replication standbys and even when database_name is
null, nothing gets appended, it's just the appendStringInfo() call
gets wasted, but that's okay.
