It strikes me that the ps_status support provides one important bit of information that is currently hard to get elsewhere; specifically, the "waiting" flag that gets added while blocked on a lock. You can find out if a process is blocked by looking in pg_locks, but that's a fairly expensive probe in itself and then you have to join to pg_stat_activity to make any sense of it. I wonder if we should add a "waiting" boolean column to pg_stat_activity? Given the new implementation of pg_stat_activity, updating such a flag would be pretty cheap. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
