I'd like to keep supporting the old pickle for data interchangeability, but default to pickle protocol 2, which has been supported by Python for several versions.

I still use pickle protocol 0, since it does not output \x00 like protocols 1 and 2. Some databases either don't provide a way to escape \x00 in SQL statements, or have nasty bugs when comparing or operating on string values with \x00 in them.
