COMMIT PREPARED — commit a transaction that was earlier prepared for two-phase commit
COMMIT PREPARED transaction_id
To commit 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 committed immediately.
All currently available prepared transactions are listed in the
pg_prepared_xacts
system view.
