You can either use the datatype "SERIAL" or if you have a way of
generating unique IDs based off of microtimes, you can get away with
putting a unique value into field "id" as it is right now.

Hi !
I´m doing my first publishing system for a last aquired boooks for a library.
the problem begin in the id field, wich i choose to be primary key and unique.
i could just insert data one time the others give me this error:
Cannot insert a duplicate key into unique index biblioteca_pkey
i use this piece of code below to insert the data:
$query = "INSERT INTO biblioteca (id, autor, titulo, editora) values ('$id',
'$autor', '$titulo', '$editora')";
$result = pg_exec($db, $query);
may i can alter the id collumn and the query to insert the data anybody
knows what exactly to do ?
Thank´s
Ângelo
