I was thinking about turning checksums on for all new databases as
long as I am able to turn them off easily, per my message prior:
http://www.postgresql.org/message-id/CAAZKuFZzA+aw8ZL4F_5C8T8ZHRtJo3cM1aJQddGLQCpEz_3-kQ@mail.gmail.com.
 An unstated assumption here was that I could apply the patch to 9.2
with some work.  It seems the revitalized interest in the patch has
raised a couple of issues on inspection that have yet to be resolved,
so before moving I'd prefer to wait for a quiescence in the patch's
evolution, as
was the case for some time even after review.

However, if we want to just hit 9.3dev with a bunch of synthetic
traffic, that's probably doable also, and in some ways easier (or at
least less risky).
