How to log query parameters instead of variables with log_min_duration_statement

Hi,
I am logging long queries with log_min_duration_statement but would like to see the parameters for parameterized queries. Eg…
Jun 28 10:21:49 dbs1 postgres[20866]: [2-1] LOG: duration: 6625.543 ms execute PRSTMT1405204512-1371060978/PORTAL1405204512-1371060978: SELECT COUNT(*)
Jun 28 10:21:49 dbs1 postgres[20866]: [2-2] FROM "XYZ123" AS "T0"
Jun 28 10:21:49 dbs1 postgres[20866]: [2-3] WHERE ("T0"."Id" = $1)
I’d like to log or find out what $1 was from the postgresql server side, not the application side. Is this possible?
Best Regards,
Max Williams

You need a more recent version of Postgres. The versions that can do
that at all (8.2 and up) will do it automatically.

I'm running 8.4.4 so you are saying this should work?
I don't really want to go to debug level logging, tried it for 5 mins and it just logs too much!
