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 .)  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.
