From actually executing the query.
From PgAdmin:
-- Executing query:
select objectid from prototype.orders
Total query runtime: 78918 ms.
Data retrieval runtime: 188822 ms.
1104379 rows retrieved.

jkr@Panoramix:~/postgresql$ time psql muntdev -c "select objectid from
prototype.orders" > output.txt
real 0m5.554s
user 0m1.121s
sys 0m0.470s
Now *I* am confused. What does PgAdmin do more than giving the query to
the database?
(BTW: I have repeated both measurements and the numbers above were all
from the last measurement I did and are about average)
