I think this patch doesn't take into account that we call
OutputPluginUpdateProgress() from APIs like pgoutput_commit_txn(). I
think we should always call the new function update_progress from
those existing call sites and arrange the function such that when
called from xact end APIs like pgoutput_commit_txn(), it always call
OutputPluginUpdateProgress and make changes_count as 0.
