The problem appears to be in the 7.4.6 backend. I did some tests
with 8.0.0rc5 and 7.4.6 and got the following results:
good 8.0.0rc5 backend, 8.0.0rc5 client
good 8.0.0rc5 backend, 7.4.6 client
bad 7.4.6 backend, 8.0.0rc5 client
bad 7.4.6 backend, 7.4.6 client
If I set log_error_verbosity to "verbose" then the 7.4.6 server
logs the following:
ERROR: 42704: no value found for parameter 1
LOCATION: ExecEvalParam, execQual.c:518
I think the following message to pgsql-commiters announces the fix
that was applied to the development branch, which will soon be
released as 8.0.0:

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
