NAME

6       ROLLBACK_PREPARED - cancel a transaction that was earlier prepared for
7       two-phase commit
8

SYNOPSIS

10       ROLLBACK PREPARED transaction_id
11

DESCRIPTION

13       ROLLBACK PREPARED rolls back a transaction that is in prepared state.
14

PARAMETERS

16       transaction_id
17           The transaction identifier of the transaction that is to be rolled
18           back.
19

NOTES

21       To roll back a prepared transaction, you must be either the same user
22       that executed the transaction originally, or a superuser. But you do
23       not have to be in the same session that executed the transaction.
24
25       This command cannot be executed inside a transaction block. The
26       prepared transaction is rolled back immediately.
27
28       All currently available prepared transactions are listed in the
29       pg_prepared_xacts system view.
30

EXAMPLES

32       Roll back the transaction identified by the transaction identifier
33       foobar:
34
35           ROLLBACK PREPARED 'foobar';
36

COMPATIBILITY

38       ROLLBACK PREPARED is a PostgreSQL extension. It is intended for use by
39       external transaction management systems, some of which are covered by
40       standards (such as X/Open XA), but the SQL side of those systems is not
41       standardized.
