No, since Git does a pretty good job of efficiently storing blobs. I would like to be able to execute
"select blob from blobs where sha=<some sha>"
but I can't justify the overhead of storing this in a database. This isn't to say I won't in the future, but if I do, I'll probably introduce a key/value DB for this, instead of using postgres. I do index blobs and diffs with lucene though. I also store the diffs in postgres.
Since Git does a very good job of storing blobs, I really can't justify using a DB just yet.

Understood.
