libpq problem

Some recent change in libpq seems to interfere with gtk.

After I tested a new pgadmin3 version on linuy yesterday, I found that 
the GUI is hanging after PQconnectdb was called. After the call, the db 
connection is fully functional, but the GUI mouse will show "waiting" 
and the program doesn't react to mouse clicks any more; screen updates 
are not performed either.

When I replace the 8.0 libpq.so* version with an older saved version 
(7.4.3 from debian installation) it works ok.
