What do you mean by 'nested table'? Maybe arrays will do what you want?
Typically (and this applies to other databases as well), this is done
using two tables and refferential integrity. IE:
CREATE TABLE purchase_order(
po_id serial CONSTRAINT purchase_order__po_id PRIMARY KEY
, customer_id int CONSTRAINT purchase_order__customer_RI REFERENCES customer(id)
, more fields...
)
CREATE TABLE po_lines (
po_id int CONSTRAINT po_lines__po_id_RI REFERENCES purchase_order(po_id)
, line_number smallint NOT NULL
, ...
, CONSTRAINT po_lines__po_id_line_number PRIMARY KEY( po_id, line_number)
)
