That's a good discussion, but it left out at least one useful bit of
info about managing large objects: there's a contrib utility
(contrib/vacuumlo) that can find and remove large objects that are not
referenced anywhere in the database. This is a good way to clean up
if you've been using large objects without any of the automatic
management techniques suggested in the GeneralBits article.
