What PG version are you using? Since 8.2 log_duration should show
parameter values. As for the other, you'd have to turn on
log_statements so that the parameters get logged in advance of the
failure. Once the transaction has failed we can't call user-defined
output functions, since they might try to do things that don't work
inside a failed transaction.
