So I guess it is impossible to be used in something to be released

I love hsqldb, and have used it some time ago. What I loved most of it
is that the DB format we used was essentially an ASCII log of SQL
commands, so that it was amazing for debugging. This formats gets
collapsed to a set of INSERTs on close/open, so it is not as bad as it
looks.

I wonder if derby has something similar, I always missed this for
debugging DB related issues when we moved off hsqldb.
