NAME¶

ROLLBACK PREPARED - cancel a transaction that was earlier prepared for two-phase commit

SYNOPSIS¶

ROLLBACK PREPARED transaction_id

DESCRIPTION¶

ROLLBACK PREPARED rolls back a transaction that is in prepared state.

PARAMETERS¶

transaction_id

The transaction identifier of the transaction that is to be rolled back.

NOTES¶

To roll back a prepared transaction, you must be either the same user that executed the transaction originally, or a superuser. But you do not have to be in the same session that executed the transaction.

This command cannot be executed inside a transaction block. The prepared transaction is rolled back immediately.

All currently available prepared transactions are listed in the pg_prepared_xacts system view.

EXAMPLES¶

Roll back the transaction identified by the transaction identifier foobar:

ROLLBACK PREPARED 'foobar';
