I just tried 300 and 512, with no apparent ill effects. Didn't do much
with the new parameters; createdb, destroydb, and the int8 user-package
and test inputs.

Don't know what "can't get above 256" actually means. Does postgres
refuse to start up, do you get core dumps, or are there more subtle
effects?? btw, I'm on a plain-vanilla dual Pentium Pro with 96MB of
(new) memory running Linux (don't choke... :)
