Here's a rebased series on top of today's a3eac988c267. I call this
v28.
I put David's pg_dump and COMMENT patches as second in line, just after
the initial infrastructure patch. I suppose those three have to be
committed together, while the others (which add support for additional
statistic types) can rightly remain as separate commits.
(I think I lost some regression test files. I couldn't make up my mind
about putting each statistic type's tests in a separate file, or all
together in stats_ext.sql.)
