Coming soon to a 7.2 near you:

regression=# select * from pg_stat_activity;
 datid  |  datname   | procpid | usesysid | usename  |          current_query
--------+------------+---------+----------+----------+---------------------------------
 400867 | regression |   29709 |      256 | postgres | select * from pg_stat_activity;
 400867 | regression |     452 |      256 | postgres |
(2 rows)

(the second backend doesn't have collect_querystring turned on, so it's
not reporting its current query...)

Hopefully, Jan will get around to writing some documentation about
this before release ;-)
