Hey folks,

   I searched the archives and didn't really come up with much, so I'm
posting my question here.

   I have two tables in the same database, whose structure I want to be
identical.  Call them 'bob' and 'test_bob' for example.

   If I make a change to the schema of 'bob', I want that exact change to
happen to 'test_bob'.  The data is irrelevant - any data in 'test_bob' is
going to be manipulated, spindled, folded, and mutilated.  The data in
'bob' must remain intact.

   For example, if I ALTER a column or ADD a column to 'bob', I need the
exact same thing to happen to 'test_bob'.

   Is this possible without the typical DROP and CREATE TABLE?  Many
thanks for any input.  :)
