ROLLBACK PREPARED transaction_id
ROLLBACK PREPARED rolls back a transaction that is in prepared state.
transaction_id
The transaction identifier of the transaction that is to be rolled back.
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.

ROLLBACK PREPARED 'foobar';
