i'll answer only to a part of your question, since i'm not sure of the other
part:
you can create a SEQUENCE with something like:
CREATE SEQUENCE "name_of_the_seq" start 1 increment 1 maxvalue 2147483647
minvalue 1 cache 1
and then add a column like:
"column_name" int4 DEFAULT nextval('name_of_the_seq'::text) NOT NULL
this column will be auto-incrementing, so when you do a INSERT you won't
have to pass any parameter for to this column.
hope this helped you,
Giorgio A.
