Thanks for fixing.

As you mentioned to me off-list about missing pg_dump support, I've gone
and implemented that in the attached patch.

I followed how pg_dump works for indexes, and
created pg_get_statisticsextdef() in ruleutils.c. I was unsure if I should
be naming this pg_get_statisticsdef() instead.

I also noticed there's no COMMENT ON support either, so I added that too.
