Manual Reference Pages - RELEASE_SAVEPOINT (7)
RELEASE_SAVEPOINT - destroy a previously defined savepoint
RELEASE [ SAVEPOINT ] savepoint_name
destroys a savepoint previously defined in the current transaction.
Destroying a savepoint makes it unavailable as a rollback point, but it has no other user visible behavior. It does not undo the effects of commands executed after the savepoint was established. (To do that, see
ROLLBACK TO SAVEPOINT (ROLLBACK_TO_SAVEPOINT(7)).) Destroying a savepoint when it is no longer needed allows the system to reclaim some resources earlier than transaction end.
also destroys all savepoints that were established after the named savepoint was established.
The name of the savepoint to destroy.
Specifying a savepoint name that was not previously defined is an error.
It is not possible to release a savepoint when the transaction is in an aborted state.
If multiple savepoints have the same name, only the one that was most recently defined is released.
To establish and later destroy a savepoint:
INSERT INTO table1 VALUES (3);
INSERT INTO table1 VALUES (4);
RELEASE SAVEPOINT my_savepoint;
The above transaction will insert both 3 and 4.
This command conforms to the
standard. The standard specifies that the key word
is mandatory, but
allows it to be omitted.
