I'd vote for different texts and different SQLSTATEs too, per other
discussion. (I think we'd decided that ERRCODE_PROTOCOL_VIOLATION
was a bad choice anyway.)
Also, I'm afraid that the above patch probably doesn't work as-is;
won't elog.c try to send the DEBUG1 message to the client? I think
you'll need some additional code to shut down error message output
first. Resetting whereToSendOutput is probably sufficient.
