You really need to have a transaction manager around when issuing
prepared transaction as failing to commit/rollback them will prevent
VACUUM and quickly lead you to an interesting situation.

I understand this problem occurs only when the user configured the application server to use distributed transactions, the application server crashed between prepare and commit/rollback, and the user doesn't recover the application server. So only improper operation produces the problem. Just setting max_prepared_transactions to non-zero doesn't cause the problem. Is this correct?
