update-record-from-instance question/gripe

Dear clsql-devel,

I have a question/gripe about update-record-from-instance. Maybe I just 
don't understand how to do what I want, but what I think I want is a 
long-lived object that gets instantiated from tables via make-instance 
or select with an open connection to a DB. Then I want to close that 
connection and re-open another connection down the line. When I try to 
update the object using update-record-from-instance, even if I supply 
the new db connection, I fail as I think it's trying to use the old 
connection. The docs for update-record-from-instance say that the db 
only applies when the object isn't already associated with a database. 
What about the case when were associated with a db via a defunct 
connection? I'd like to be able to write this back to the database 
without having to go through the trouble of making a new object. Does 
this make sense?

Thanks,

Cyrus
