Alas, no trigger, constrainst, foreign keys, indixes (have I forgotten
something?)

All queries are slow. E.g (after vacuum):

select objectid from prototype.orders

Explain analyse (with PgAdmin):

Seq Scan on orders  (cost=0.00..58211.79 rows=1104379 width=40) (actual
time=441.971..3252.698 rows=1104379 loops=1)
Total runtime: 5049.467 ms

Actual execution time: 82163 MS (without getting the data)
