Sometimes it is helpful to be able to rename a table in PeopleSoft. I find when dealing with duplicates in tables during upgrades, you can rename a table to a temporary table and then re-create the table in question and then simply do an insert into the new table from the temporary table using a select distinct statement.

SQL SERVER:
sp_rename ‘TABLENAME’, ‘NEWTABLENAME’

ORACLE:
alter table tablename rename to newtablename
