How to log full substituted queries?

I'm trying to debug some queries and have

log_statement = 'all'

in my postgresql.conf. When I look in the resultant log file, I see
entries like this:

INSERT INTO servers (
hostname, last_modified, serial,
asset_tag, grid, admin )
VALUES
( $1,CURRENT_DATE,$2,
$3,$4,$5
)

What I'd actually like to see is the fully-parsed version, e.g.

INSERT INTO servers (
hostname, last_modified, serial,
asset_tag, grid, admin )
VALUES
( 'loki', CURRENT_DATE, '10-129CF',
'213457','23G','ut1'
)

...so I can see what the client is actually sending. Is there a
way to do this?
