Since we went to Postgres with the 0.6 api the planet dump should be a consistent snapshot of the database. If it isn't then there is a bug that needs to be dealt with. I suspect what you are seeing is not a result of an inconsistent snapshot however, but simply of corrupt data (probably created before the 0.6 api) that exists in the database.
