Do you have some foreign keys pointing in the other direction? In other words, is there another table such that a delete on sensors causing a delete (or a check of some key) in another table? EXPLAIN doesn't show these. And that might be a big table missing an index. ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
