Unlike Access' Auto_Increment fields, which are always read-only, PG (& most
other databases) uses sequences, which _can_ get the next number, or can
allow you to supply a number.
In my Access front-ends, I usually hide this column in datasheet view, and,
change the properties of the textbox on form view to mark it as read-only.
Very easy to do.
