Every client I use is affected by the problem.
The main client is a 
java program that connects to the db through jdbc. Even writing a 
simple program that only performs a select query doesn't solve the 
problem.
A select query issued using pgAdmin takes the same time and so 
does the show data command in pgAdmin
Maybe this is a problem related 
to the win32 version of postgres (I haven't tried to run this db under 
linux)
