Syntax:
RENAME TABLE tbl_name TO new_tbl_name
    [, tbl_name2 TO new_tbl_name2] ...

The rename operation is done atomically, which means that no other
session can access any of the tables while the rename is running. For

another table new_table that has the same structure but is empty, and
then replace the existing table with the empty one as follows (assuming
that backup_table does not already exist):
