You could save yourself a lot of time if you enabled warnings from your C compiler (eg, -Wall for gcc) and then paid some attention to them. The last parameter to array_ref is a bool *, not a bool, and I have no doubt that the backend is crashing while trying to dereference "false". (Another problem is that the fourth parameter should be -1 not VARSIZE.) 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
