Обсуждение: 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... -- Tatsuo Ishii

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... -- Tatsuo Ishii

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... regards, tom lane
