Logging/Viewing parameters of a prepared statement

I’m using Version-8.1.4 and JDBC-3 jar

I call a db function from my java code, using a prepared statement.

When I look at the logs of postgres in data/pg_log, the statement executed appears like for example

“select * from get_user($1)”

It would be nice if I can somehow know the value of $1 passed in.  So Ideally a statement like

“select * from get_user(1234)” (where 1234 is $1), would be more helpful. 

This is all in efforts to make debugging easier.  For instance using MS SQL Server’s Profiler, you can monitor

all statements executing on the db.  I’m trying to achieve that on postgres.

I’ve configured the log_statement=’all’ in postgresql.conf.

Thanks
