[Zope] Zope 2.8 and conflict errors

[Stefan H. Holek]

Well, you know...

In this one project, we had an interesting (cough) situation with  
PostgreSQL + psycopg, where we would see plenty of write conflict  
errors coming from the DB connector.

Turned out PostgreSQL has kind of an "optimistic" transaction  
control, where the DB server returns something like "couldn't really  
resolve this concurrency issue, please retry" to the DB connector,  
and psycopg would translate that into a ZODB ConflictError to make  
the ZPublisher retry the transaction. Not kidding.

So, while I don't know much about the internals of DCOracle you may  
want to make sure the ConflictErrors are due to the ZODB at all.
