sorry, it took me a while to get back to the machines again, however, here 
is the error output cut 'n pasted:

So, after submitting the same query, for about 10 times, then instead of the 
result set, the following was shown in the sql output window of pgadmin3:
********** Error **********

Then, when I try to submit the query again, an error popup window shows up, 
stating the following:

An error has occurred:

no connection to the server
and at the same time, on the console the following appears:

Xlib: sequence lost (0xd5bf8 > 0xc5bfa) in reply type 0xf!
Xlib: unexpected async reply (sequence 0xc5c81)!

When I then try to close the error window, it is not closing, I klick 
the "close" or "ok" or however the button is called, the button several 
times, and then pgadmin3 disappears at all, leaving the following message on 
the console:

The program 'pgadmin3' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAtom (invalid Atom parameter)'.
  (Details: serial 967950 error_code 5 request_code 18 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I also retested, with psql from commandline, using the same query,
and I was able to issue it about 50 times in a fast row, before I stopped 

I also tried pgadmin 1.8.1, and I did ran into the same problem, but it 
seems that the problem does not occur so fast, but maybe that was just
