I am trying to find the most efficient way to keep two databases in
sync.  There are multiple tables in the database and each row has a
"dirty" flag if something has changed since the last sync.  I am
pickling session objects and passing them back and forth to
applications that are managing each of the databases.  While it is
working, I have code like:

for col_name in [col.name for col in klass.c]:
     setattr(db1_row_obj, col_name, getattr(db2_row_obj, col_name))

As you can see, I am just setting each column in an row needing
updating to the value of each column in the "changed" row.

My question is whether there is some way to just force SA to update
every column in a table row from a session query row object.  Since
the row object containing the updates will be an unpickled object from
another database that was merged into the current session, it will
look like nothing in that row object has changed but I want to force a
database update and have the updated row overwrite everything in that
row in the database.  There is a uuid that allows the rows to be
matched.  Thanks for any help.
