RELEASE SAVEPOINT
RELEASE SAVEPOINT — destroy a previously defined savepoint
Synopsis
RELEASE [ SAVEPOINT ] savepoint_name
Description
RELEASE SAVEPOINT destroys a savepoint previously defined in the current transaction.
Destroying a savepoint makes it no longer usable 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). Destroying a savepoint when it is no longer needed allows the system to reclaim some resources before the transaction ends.
RELEASE SAVEPOINT also destroys all savepoints established after the savepoint being released.
Parameters
savepoint_name
The name of the savepoint to destroy.
Notes
Specifying a savepoint name that was not previously defined is an error.
Savepoints cannot be released when the transaction is in an aborted state.
If multiple savepoints have the same name, only the most recently defined one will be released.
Examples
# Establish and 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.
