Hello all,I have a problem invocating SELECT statements using Java JDBC driver having a remote communication between PostgreSQL database client-server through Internet.
You may want to re-run with logLevel=2 as a connection parameter; then the driver will log all the network I/O it is doing.
Without a detailed TCP trace I can't be sure but it sounds like perhaps you have a path MTU discovery problem between the server and client, or something similar. I suspect that when you turn on driver debugging, you will see the driver just stop receiving new data from the network at some point.
(if you like, mail me a tcpdump or wireshark packet capture off-list - ideally one capture from each end of the connection - and I'll take a look)
