If your need-for-speed is so high, I would suggest using 8.3 or at least
looking at the 8.3 documentation.
This release is very nearly production and is much faster than 8.1 or
8.2. You may not have realised that Postgres dot releases are actually
major releases and have significant speed differences.
There's not much to be done about the overheads you mention, so best to
concentrate your efforts on index planning for your most frequently
executed queries.
