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';
