So we need to extend an infrastructure such that we can check the status of the transaction for which we are decoding the change. Also, I think we need to handle the ERRCODE_TRANSACTION_ROLLBACK and ignore it. I have attached a small patch to handle this which can be applied on top of your patch set. -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
