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: http://archives.postgresql.org/pgsql-committers/2004-08/msg00028.php -- Michael Fuhr http://www.fuhr.org/~mfuhr/ ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to majordomo@xxxxxxxxxxxxxx)
