Can we adjust postgres logging to also dump the bind variable data when an error occurs

I am using Postgres version 8.0.3.  I have noticed that when I set the log_statement parameter to 'all', I get the values for the bind variables.  Is it possible to get all of the same information that I get when I set log_statement to 'all' just for the statement that has an error?  I don't want to clutter up my log file with this detail information for all statements, just those that produce an error.

 

Thanks for your help.
