RELEASE SAVEPOINT - destroy a previously defined savepoint
RELEASE [ SAVEPOINT ] savepoint_name
RELEASE SAVEPOINT 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 may allow the system to reclaim some resources earlier than transaction end.
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.
To establish and later destroy a savepoint:
BEGIN; INSERT INTO table1 VALUES (3); SAVEPOINT my_savepoint; INSERT INTO table1 VALUES (4); RELEASE SAVEPOINT my_savepoint; COMMIT;The above transaction will insert both 3 and 4.
