Data retrieval runtime: 188822 ms.
1104379 rows retrieved.

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)
