"mirroring" a table - PostgreSQL 7.3.2

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. :)

Benny
