The PG driver seems to be using the standard Socket java
interface, so there's little chance it has anything to do with
it. I would try to run a local Java program using a Socket object
to connect to a fake port on the same machine, for example you
could base on network connection code from:


http://code.google.com/p/androidnetworktester/source/browse/trunk/src/org/gc/networktester/tester/TcpConnectionTester.java

Btw, one per 100K connections means you keep on creating new
connections. This usually has very poor performance. You should
use a connection pool.
