Great! Thanks much!

Ah. If you're using GIT, you might find it more convenient to pull/merge
from http://git.0ape.com/postgresql/
or browse through gitweb: http://git.0ape.com/?p=postgresql;a=shortlog;h=refs/heads/cleanup
http://git.0ape.com/git-browser/by-commit.html?r=postgresql
though this is the first time I've set up gitweb so it might have rough edges.

Ah yes. Let me guess, HAVE_INT64_TIMESTAMP was defined. I believe
the later refactoring patch also avoids that bug; but yes, I obviously
should have had it working in this patch.
This fix was simple (can be seen on gitweb here: http://tinyurl.com/5fxeyw)
and I think I've pushed the updated patches to my website.
Once I fix the stylistic points you mentioned below I'll post
the resulting patch to the mailing list.

Totally agree with all your style suggestions. Will send an update
a bit later today.
