6 minutes read

To cancel a PostgreSQL transaction and do nothing, you can simply issue a ROLLBACK command without any further instructions. This will effectively cancel the current transaction and revert any changes made, but no additional actions will be taken. This approach is useful when you want to abort a transaction without triggering any specific actions or commands to be executed. By using the ROLLBACK command on its own, you can quickly and easily cancel the transaction and return to the previous state without performing any additional operations.
