PostgreSQL Current Transaction Is Aborted

PostgreSQL Current Transaction Is Aborted – Error Explained

In PostgreSQL, you may see this error:

ERROR: current transaction is aborted, commands ignored until end of transaction block

This means that one of your previous SQL statements inside the transaction has failed, and PostgreSQL automatically marks the entire transaction as aborted. Until you ROLLBACK or COMMIT, all further commands in that transaction will be ignored.

The PostgreSQL current transaction is aborted error is very common when running scripts, batch jobs, or complex queries.

Why Does This Error Happen?

  • A query failed inside a transaction (e.g., constraint violation, syntax error).

  • Application didn’t handle exceptions properly.

  • Using manual transactions without error checking.

  • Locks or invalid data caused query failures.

7 Proven Fixes for PostgreSQL Current Transaction Is Aborted
1. Rollback the transaction
ROLLBACK;

This resets the transaction state and allows new queries.

2. Use COMMIT after successful queries

If all queries succeeded, commit:

COMMIT;
3. Run queries outside transactions

For one-off commands, avoid wrapping in a transaction block.

4. Check for constraint violations

Example: unique key error, foreign key violation. Fix the root cause and retry.

5. Use exception handling in PL/pgSQL
BEGIN
-- query here
EXCEPTION WHEN others THEN
ROLLBACK;
END;
6. Enable ON_ERROR_ROLLBACK in psql

In interactive sessions:

\set ON_ERROR_ROLLBACK on

This allows partial rollback instead of aborting the full transaction.

7. Improve application error handling

  • Always log errors.

  • Rollback transactions before retrying.

  • Use connection pooling wisely.
