pgAdmin3 is just another app, concerning the database connection. So if 
pgAdmin3 suffers from broken links, any other libpq app would too. It 
would make sense to implement this in libpq.
If we wanted to implement this in pgAdmin3, we'd need a global keepalive 
thread, scanning all connections if a keep alive query is needed, 
interlocking with a semaphor to prevent interference with wanted 
queries. This thread also could silently handle reconnects.
