ERROR: current transaction is aborted in PostgreSQL

Why PostgreSQL Refuses to Continue After an Error

If you work with transactions in PostgreSQL, the message ERROR: current transaction is aborted, commands ignored until end of transaction block is likely familiar. While it appears constantly, its underlying mechanism is often misunderstood. The message is not random — it reflects how PostgreSQL enforces atomicity inside a transaction.

The Rule Behind the Error

In PostgreSQL, every single statement runs inside a transaction, even if you don't explicitly open one. When you need multiple statements to behave as one unit, you wrap them in BEGIN and COMMIT, guaranteeing that either all operations take effect or none do.

The moment a statement inside the block fails, PostgreSQL marks the entire transaction as aborted. From then on, the server ignores further commands until the transaction ends. Even if your application issues a COMMIT, PostgreSQL will not honor it — it converts it into a ROLLBACK. The application, therefore, must check whether the transaction actually committed, rather than assuming that calling COMMIT is enough.

Why This Behavior Exists

This strict handling is not a limitation but a safety measure. Once an error occurs, the state of the transaction may be inconsistent. Allowing further statements to run could produce unpredictable results or leave partial changes. By halting all work until the transaction ends, PostgreSQL avoids compounding the problem.

There is also a practical consideration for database logs. PostgreSQL logs errors by default. If a long batch job runs millions of statements inside a single transaction and does not stop on failure, each ignored statement produces a separate log entry. This can overwhelm your log files with repetitive, meaningless content.

The Only Way to Recover

If a failed statement should not doom the entire transaction, the only tool available is SAVEPOINT. A savepoint acts as a subtransaction marker: you can set one before a risky operation, and if that operation fails, you can roll back to the savepoint. The transaction then remains usable, and you can still commit the successfully completed parts. Without savepoints, an aborted transaction cannot be rescued — the only options are rolling it back entirely or letting PostgreSQL finish it with an automatic rollback.

Understanding savepoints and how they interact with subtransactions is key to writing resilient, efficient code that handles errors gracefully without sacrificing the atomicity guarantees of the transaction model.
