I can add to this that the issue occurs only on consequent appends.
Here's the excerpt that leads to the IntegrityError, demonstrating this.
collection = Collection()
session.save(collection)
session.flush()
vinyl = Vinyl()
colletion.records.append(vinyl)
well, it will be useful if when a m/anytoone relation (i.e. plain
reference) klas.descriptor is used in an expression context, to yield
just the respective column.

Hi, I have been thinking about logic for a second DSN for failover
with some time interval to try the second source. If I am using
asynchronous replication, time is required to allow slave to become
master.
For application logic, I don't want to tolerate a failure. Rather, I
want to log

Hi Michael. I appreciate your reply. Did not know if it was something
you'd want for consider for stock sqlalchemy. Incorporating into app
is easy enough. I like the transparency of your recommendation. Many
thanks.

it will be and I'll probably just

thanks for this example. There's several issues with this mapping.
The most crucial, although not the issue in this specific example, is
that the relations table is used both as the secondary table in a
relation(), and is also mapped directly to the Relation class. SQLA
