One of the suggestions handed to me a long time ago for speeding up PG
on FreeBSD was to double the default blocksize in PG.  I tried it, but
found not a significant enough speed up to make it worth the trouble
to remember to patch every version of Pg during the upgrade path (ie,
7.4.0 -> 7.4.2 etc.)  Forgetting to do that would be disastrous!
