So this is what you did when you started with the Alpha 1 database, correct?

When you went to Alpha 2 you just installed the new program over the 
existing Alpha 1, but left the data directory as is and then ran into 
the error, correct?

You then did a dump of the Alpha 1 or other(?) existing database and 
then a restore into the Alpha 2(the reload above) at which point the 
error went away, correct?
