Fix the tip version. You'll need fromcvs and rcsparse from
<http://ww2.fs.ei.tum.de/~corecode/hg>. We already know that the version
used on the community repo is broken. The version I am using on my
github mirror is holding up OK. There is a recipe for setting up a
mirror on my blog:
<http://people.planetpostgresql.org/andrew/index.php?/archives/74-Gory-details.html>.
Of course, we might also find some other brokenness if we try to import
all the tags. Also, be aware of this (from
<http://cvs2svn.tigris.org/cvs2git.html>):

Differences between CVS and git branch/tag models: CVS allows a
branch or tag to be created from arbitrary combinations of source
revisions from multiple source branches. It even allows file
revisions that were never contemporaneous to be added to a single
branch/tag. Git, on the other hand, only allows the full source
tree, as it existed at some instant in the history, to be branched
or tagged as a unit. Moreover, the ancestry of a git revision makes
implications about the contents of that revision. This difference
means that it is fundamentally impossible to represent an arbitrary
CVS history in a git repository 100% faithfully.
