invalid transaction state

Category: Invalid Transaction StateVersions: All Postgres versions

What this means

SQLSTATE 25000 is the generic invalid transaction state code. It is raised when a command is executed that is not valid in the current transaction state — for example, issuing a data-modifying statement after an error that requires rollback.

Why it happens

1Attempting to execute SQL after a failed statement that has put the transaction in a must-abort state
2Transaction state command used in an invalid context

How to reproduce

Executing SQL after a statement error without rolling back.

trigger — this will ERROR

BEGIN;
SELECT 1/0; -- ERROR: division by zero — transaction is now aborted
SELECT 1;   -- ERROR: 25P02 (transaction aborted)

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

Fix 1: ROLLBACK the transaction and retry after any statement error

When a statement error puts the transaction in the aborted state.

fix

ROLLBACK;
-- start fresh
BEGIN;
-- retry

Why this works

After any error in a transaction block, the transaction must be rolled back before new work can begin.

Fix 2: Use SAVEPOINTs to allow partial recovery within a transaction

When some work must be preserved despite individual statement errors.

fix

BEGIN;
SAVEPOINT sp1;
-- risky operation
-- if it fails: ROLLBACK TO SAVEPOINT sp1;
RELEASE SAVEPOINT sp1;
COMMIT;

Why this works

SAVEPOINTs allow rolling back to a known good state within the transaction without aborting the entire block.

What not to do

✗

Continue executing statements after a transaction error

Why it's wrong: The transaction is in an aborted state; all statements are rejected until ROLLBACK is issued.
