Also, if the table and column already exist, you can alter the table's column to become an auto-incrementing column.

http://www.postgresql.org/docs/8.3/static/datatype-numeric.html#DATATYPE-SERIAL

You can substitute the create table statement with an appropriate alter table alter column statement from the example
demonstratedin the above link.
