Changes the name of the sequence being altered. See the RENAME
    statement for further discussion. If the new name is the name of
    a synonym then an error will be raised.

    The new name must not exist as the name of an existing sequence,
    synonym, table or view. You may not rename a system sequence.

    The RENAME TO clause requires synonyms be enabled for this
    database. Refer to the ALTER DATABASE SYNONYMS ARE ENABLED
    clause. Note that these synonyms may be deleted if they are no
    longer used by database definitions or applications.
