Those log messages do appear to match the theory, but in the case at hand, the server seems to have hung up without throwing any error. However, we'd reproduce that if the apparent "message length" was less than 1GB (assuming the server process could malloc that much memory). That'd occur for any second byte less than 0x40, such as an ASCII digit. regards, tom lane
