The easiest way in PostgreSQL is to simply make the field a serial type.
CREATE TABLE mytable ( id SERIAL PRIMARY KEY, myname TEXT);

Again, the table definition can handle this.
CREATE TABLE mytable ( id SERIAL PRIMARY KEY, mydate DATE DEFAULT CURRENT_DATE, myname TEXT);
You should check out the docs on the web site. They are quite comprehensive.
