SELECT fields FROM partitioned_table WHERE primarykey = $1; it doesn't optimize this very well and ends up looking at all the sub-table indicies. ir you instead execute the statement SELECT fields FROM parritioned_table WHERE primarykey = constant; he says the planner will go straight to the correct partition. i haven't confirmed this for myself.
