A look at the code revealed that the temp tables were created via normal

going away on Postgresql-8.2.x after the connection is closed?
You aren't the first to report such a thing, but nobody has the foggiest
idea how it could happen short of a backend crash. Have they had any
crashes lately (or more specifically, around the mod times of those
files, if you checked them)?
Also, were the pg_temp schemas you zapped particularly high-numbered?
Low-numbered ones would get cleaned out on the next use, but if the
crash happened at a peak in the number of active backends it's easy
to believe the files might hang around for awhile.
I inquired whether there had been crashes and they indicated no. I've
requested a mining through the logs to see if there were any backend crashes,
but probably won't get the info till next week.
Looks like the highest was pg_temp_534.
