[Bucardo-general] could not serialize access due to read/write

Ah...you could try lowering the isolation level in that case. 
Look inside Bucardo.pm and change all occurances of:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE

to:

SET TRANSACTION ISOLATION LEVEL REPEATABLE READ

Those two are very different in 9.1, but were the 
same before then. See:

http://blog.endpoint.com/2011/09/postgresql-allows-for-different.html

Please let us know if that changes things for you, because 
if it does, we'll probably have to at least add a config 
variable in there.
