Not sure after that... That seems to eliminate the possibility that the problem is on the server side. I'd suggest trying to get a stack trace from the client to figure out what it's doing. BTW, have you looked into the theory that it's triggered by total data volume rather than number of columns? That is, try selecting all the columns but use LIMIT to reduce the number of rows fetched? 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
