Hi, I have a question about getting some information about database changes.
Let's suppose I have a particular transaction ID that I happen to know has been rolled back. Is it possible to ask the database if there have been any committed transactions subsequent to that rolled-back transaction? Basically I'm would like to know if I will see the same state of data that I could see at the beginning of that transaction in the transaction I am in right now. I am using Postgres 9.2, but if it's only possible in a later version I would be interested in knowing that too. Thanks very much! -- --Dave Peticolas
