annotate src/db.cpp @ 3603:a3ef3e3e0ee2 draft

Handle incompatible BDB environments Before, opening a -datadir that was created with a new version of Berkeley DB would result in an un-caught DB_RUNRECOVERY exception. After these changes, the error is caught and the user is told that there is a problem and is told how to try to recover from it.
