I am debugging the driver myself, I am looking into the PhantomReferences that I think may be the cause of the problem (the problem seems to me loosely related with the garbage collector frequency)

If I do the "set statement_timeout = 60000" on that connection I suppose that after I release this connection back to the pool and another thread fetches it the statement timeout will remain set ... is it not?

But it is good to know that I am not crazy....

Unfortunately setQueryTimeout() is currently a no-op. As a workaround,
set the server's statement_timeout variable.

The driver is waiting for results from the server. Either the query is
still running or something has got confused about what's happening at
the protocol level.

Can you reproduce this with loglevel=2 set (as a URL parameter, see the
driver docs)? Or a tcpdump/snoop/ethereal capture of the connection with
the server when it gets stuck would also be useful. Also, if you could
attach to the corresponding backend via gdb or similar and get a stack
trace that may help.
