I'm trying to read/write large objects via libpq. I encapsulated the operations in a transaction but I wanted to put a savepoint before doing any operations, so I can do a rollback in case anything fails without breaking the current transaction. Now, when sth. actually fails and the transaction is rolled back to the savepoint, the next commit results in a warning: Snapshot reference leak: Snapshot 0xb5e4b0 still referenced I'm not sure what to make of that. Can it be ignored? Is rolling back large object operations not possible?
