But my initial question was about a query that does not produce data at
all (well, a response from the server saying it is finished). I broke
that query off after several hours.

I am now running the query from my initial question with psql (now for
>1 hour, in a transaction, fsyn off).

Some statistics :

uptime:
06:35:55 up  9:47,  6 users,  load average: 7.08, 7.21, 6.08

iostat -x -k 1 (this output appears to be representative):

avg-cpu:  %user   %nice    %sys %iowait   %idle
           1.00    0.00    0.50   98.51    0.00
