Need query parameter in logs

[Robert Perry <rlperry@xxxxxxxxxxxxxxxxxxxxxxxxx>]

	I am trying to help debug a application that is deployed in the  
field. I suspect that it is sending some unexpected values to some  
stored procs, but the logs look very much like:

Feb 9 14:29:26 localhost postgres[3138]: [122-1] LOG: statement:  
Select * from game_state_set_disqualified( $1, $2, $3, $4 )

	How can I find out what $1, $2, $3, $4 are short of recompiling the C 
++ client code?

Thanks
Robert Perry
