Re: log bind parameter values on error

Here's a curious thing that happens with this patch.  If you have
log_duration set so that parameters are logged during the bind phase,
and then an error occurs during the execution phase but you don't have
log_parameters_on_error set true, the second error will log the
parameters nonetheless ... because they were saved in the ParamListInfo
struct by the errdetail_params() call in the check_log_durations block
during bind.

I'm not sure this is a terrible problem, but does anybody think we
*not* save params->paramValuesStr across a log_duration when
log_parameters_on_error is not set?

(I think this is somewhat equivalent to the "was_logged" case in
check_log_duration itself.)
