Dropping a column

I know how to drop a column from a table by selecting into a new table the columns I want to keep. However the problem I am running into is that some of the columns in my original table have certain attibutes (auto incrememnting, default values, etc) however the method of:

SELECT id,name,description INTO TABLE temp FROM origtable;
DROP TABLE origtable;
ALTER TABLE temp RENAME TO origtable;

Preserves my data but not the extra column information (at least according to a \d tablename)

Anyone know if it is possible to do this?

Thanks.
