RELEASE SAVEPOINT(7)              PostgreSQL 14.15 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 most recently defined unreleased one
       is released. Repeated commands will release progressively older savepoints.

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.
