Why does PostgreSQL say the current transaction is aborted after a failed statement?
KitForma editorial guide. An error inside a transaction leaves it in a failed state until rollback. Sending unrelated statements on the same connection does not clear that state.
Step-by-step answer
An error inside a transaction leaves it in a failed state until rollback. Sending unrelated statements on the same connection does not clear that state.
Roll back the transaction before returning the connection to a pool. If a recoverable sub-operation is expected, create a savepoint before it and roll back to that savepoint on failure. Test a constraint violation followed by another query to verify cleanup. Do not retry only the last statement if earlier transaction assumptions may be invalid. Pool reset behavior must be explicit so the next request never inherits a failed transaction.
