log_min_error_statement and parameters value

Hi,

In PostgreSQL 8.2, log_statement display actual parameters value which is 
very neat as in
DETAIL:  parameters: $1 = '1', $2 = NULL

Currently I used log_statement='all' to display all statements and their 
parameters but
that produced a lot of output and I am really only interested in the 
statements displayed with log_min_error_statement.

Is it possible to set log_min_error_statement to display the parameters 
value?

Thanks,
