Increment primary key

The easiest way is to do it in the CREATE TABLE statement:
CREATE TABLE mytable (id SERIAL PRIMARY KEY, name text);

That will make id an integer, automatically create a separate SEQUENCE, and bind
id to that sequence so that it is incremented properly.
The online docs elaborate on this; look for CREATE SEQUENCE, CREATE TABLE, and
SERIAL. Best of luck!

Subject: [GENERAL] Increment primary key

Hi

I created a table and the primary key must increment
automatically with e.g 1 each time I insert a new row.
How do I write the psql code to make this happen?
