MIGRATING FROM POSTGRES VERSION 1.0

-----------------------------------

Version 1.02 is mostly backward compatible with Version 1.0, but the database

format is incompatible, so if you have databases that you use with Version

1, you need to convert them before you can use them with Version 1.02. Once

you do that, you won't be able to use them with Version 1 anymore.

Version 1.02. Once you do that, you won't be able to use them with Version 1

anymore.
