Why must there? Using a sequence is the correct way to do it. To
automate the process, declare a column of SERIAL type. (SERIAL is
shorthand for creating a sequence and attaching it to the column's
default.)

Hi Oliver,

Yes! Thats what I was looking for. I've seen it in the documentation but
could'nt remember how it works. Thanks for the tip :-)

There are other options. But if you don't have any other requirements than
what you mentioned, you should use sequence/serial.
