You don't talk about integrity on this page. The ext2fs async mount may
lose the FS in the power failure case, ufs+SU doesn't. You also present
only the ufs sync and async numbers, but not the noasync (default)
numbers, you should either present them or add a note why you don't
present them.

About the "without debugging" description: did you really only remove
INVARIANTS? If yes: you also need to remove WITNESS.

I don't know if 5.1-RELEASE has malloc debugging enabled, but to be on
the safe side you should maybe do a "ln -s aj /etc/malloc.conf" before
you start PostgreSQL.
