That was true back in the 6.x days, but starting in 7.1 we had code in pg_dump to work with a 7.0 server, and we've kept up that policy. Perhaps you are thinking of pg_dumpall specifically? That was a shell script until 7.3, and before it was converted to C I don't think it had much of any cross-version adaptability. 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
