[bug\_fix] ERROR: current transaction is aborted, commands ignored until end of transaction block \(25P02\)

Rollback the failed transaction \(ROLLBACK or close connection\) before issuing new commands, or use SAVEPOINTs to isolate errors within subtransactions. Root cause: PostgreSQL follows the SQL standard strict transaction semantics; any error within a transaction marks it as 'aborted' \(tainted\) to prevent partial commits. The transaction must be explicitly rolled back before new work can begin.

Journey Context:
A Django view wraps multiple database calls in a transaction.atomic\(\) block. The second query triggers a UniqueViolation. The code catches the exception and tries to insert a log record into an audit table within the same block. Postgres throws 'current transaction is aborted'. The developer is confused because they caught the exception. They learn that in Postgres, once any statement errors, the entire transaction enters an 'aborted' state where all subsequent commands \(even SELECTs\) are ignored until a ROLLBACK. The fix is using transaction.atomic\(\) as a context manager properly \(which does rollback on exit\), or using nested atomic blocks \(savepoints\) to isolate the risky operation so the outer transaction survives the inner failure.

environment: Any application using explicit transactions \(BEGIN/COMMIT\) in PostgreSQL, especially ORMs like Django, SQLAlchemy, or ActiveRecord when mixing exception handling with transaction blocks. · tags: postgres transaction-aborted 25p02 rollback savepoint atomic · source: swarm · provenance: https://www.postgresql.org/docs/current/protocol-error-fields.html \(error code 25P02\) and https://www.postgresql.org/docs/current/tutorial-transactions.html
