You are probably correct, but I was thinking more of "reports". Like show
me the # of commits per week for user xyz between June 2004 and July 2004.
Or a graph of commits by programmer over a time period. The schema would
likely be able to provide this information rather easily.

My point was that mucking with any database should be a last resort. If I
had to do it, I would rather do it with my SQL database. Funny that you
should reply, because I almost mentioned your name as being 1 of maybe 2
people in the world capable of fixing a Subversion BDB database.

I actually think that fsfs now has the best backup story because it lends
itself so well to an incremental backup. However, most enterprises
already have database backup and recovery in place and would feel most
comfortable with that as the solution.
