A table may be safely re-named by passing the RENAME clause to the ALTER TABLE command. The following is the syntax to re-name a table where table_name is the name of the table to be renamed, and new_table_name is the desired new name for the table:
ALTER TABLE table_name RENAME TO new_table_name
A table may be arbitrarily re-named as many times as you like without affecting the data. This may of course be a dangerous thing to do if you are dealing with a table which an external application relies on.
