Well, as the reader that started this all ;-) should I be worried?  I
don't see any obvious problem with the way 8.4.0 is working.  Nearly
every web page on my server is stored in postgres, and we're still
churning out pages, no problem.

Should I do a pg_dump and reinstall?  Roll back to 8.3.7?  Or just
relax, don't worry and have a sparkling adult beverage?

Thanks,

Jeff (proceeding with relaxing, not worrying, and so on)
