savepoint with the same name is established. In

<productname>PostgreSQL</>, the old savepoint is kept, though only the more

recent one will be used when rolling back or releasing. (Releasing the

newer savepoint will cause the older one to again become accessible to

<command>ROLLBACK TO SAVEPOINT</> and <command>RELEASE SAVEPOINT</>.)

Otherwise, <command>SAVEPOINT</command> is fully SQL conforming.
