Hi all, I know this sounds suspiciously like a homework course; but, it is not.

release_savepoint
RELEASE SAVEPOINT(7) PostgreSQL 9.2.7 Documentation RELEASE SAVEPOINT(7)NAME
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 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.
RELEASE SAVEPOINT also destroys all savepoints that were established after the named savepoint was established.
PARAMETERS
savepoint_name
The name of the savepoint to destroy.
NOTES
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.
EXAMPLES
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.
COMPATIBILITY
This command conforms to the SQL standard. The standard specifies that the key word SAVEPOINT is mandatory, but PostgreSQL allows it to be
omitted.
