I copied all these, and my 8.2.x still likes the bitmap scan a lot
better than the seqscan.  Furthermore, I double-checked the CVS history
and there definitely haven't been any changes in that area in REL8_2
branch since 8.2.3.  So I'm a bit baffled.  Maybe the misbehavior is
platform-specific ... what are you on exactly?  Is there anything
nonstandard about your Postgres installation?
