Well, you could change the error report in postmaster.c to show the
specific protocol version code it's receiving (7.4 and up do this,
but it hadn't occurred to us as of 7.3). I have little doubt what
you will find though. Maybe what you really want is to enable
log_connections so you can find out where the problematic connections
are coming from.
