It seems my commit fixed the issue.
https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=18f7f632de982d8fb5d0da2f2fdc48e26ac467e7

So, I continue the review.

+  <para>
+   This feature requires <xref linkend="guc-replication-delay-source-cmd"> to be configured
+   for monitoring replication delay from replicas.
+  </para>

Why this feature requires replication_delay_source_cmd to be set? Why
can't we enable the feature as well when delay_threshold_by_time > 0?
Both replication_delay_source_cmd and delay_threshold_by_time should
provide standy delay in time, which provides enogh information to
run the feature.
