If you want the exact same table including constraints I am amazed the no one has mentioned the following method.
Create a table from an existing table using following syntax:
CREATE TABLE A as B with no data;
If you wanted all of the rows, then you could use WITH DATA which is pretty fast because it simply copies the existing blocks (not row
level - no SELECT) and assigns them to the new table. When using WITH NO DATA there is no need to copy anything except the entire table
definition.
