statistics collector

Hi,

There seems no docs about statistics collector. Especially I see
following in guc:

#ifdef BTREE_BUILD_STATS
#show_btree_build_stats = false
#endif

What is it? No conifgure option, no ifdef in pg_config.h...

Please ignore this. I noticed after postings that it does nothing with
the new statistics collector.

Anyway, I see no docs for the statistics collector...

That's not new stats-collector stuff, that's ancient undocumented btree
cruft (possibly dating back to Berkeley). Jan deserves blame for the
poor state of documentation of the stats collector, but not for this ;-)

What I've been able to deduce about the stats collector is documented
now in the Admin Guide...
