I don't believe you can specify types or constraints. Also, if you specify
the name of each column in parens, PostgreSQL seems to get confused if you
do a SELECT * following AS, rather than specify each table name as well
(as of 7.1.x, I get ERROR: CREATE TABLE/AS SELECT has mismatched column
count - is this a known bug?)

I believe this should work, though you lose the UNIQUE constraint:

CREATE TABLE employee_backup AS SELECT * FROM employee;
