Ok, we're both confused I think... I thought you were talking about the
pg_stat* views, which depend on the statistics collector (that's what
the stats_* parameters control).

That actually has nothing at all to do with pg_stats or pg_statistics.
Those deal with statistics about the data in the database, and not about
statistics from the engine (which is what the pg_stat* views do...).

If you want to know about pg_stats, take a look at
http://www.postgresql.org/docs/8.2/interactive/view-pg-stats.html ...
but normally you shouldn't need to worry yourself about that. Are you
trying to debug something?

Information about the backend statistics can be found at
