COMMIT PREPARED

Name

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

Synopsis

COMMIT PREPARED transaction_id

Description

COMMIT PREPARED commits a transaction that is in prepared state.

Parameters

transaction_id: The transaction identifier of the transaction that is to be committed.

Notes

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.

Examples

Commit the transaction identified by the transaction identifier foobar:

COMMIT PREPARED 'foobar';
