Remember our previous discussions about this point: the spec's NEXT VALUE FOR construct is *not* equivalent to nextval, because they specify that the sequence advances just once per command even if the command says NEXT VALUE FOR in multiple places. This means that NEXT VALUE FOR is effectively both nextval and currval; the first one in a command does nextval and the rest do currval. Accordingly, I think it's reasonable to read the spec as saying that USAGE privilege encompasses both nextval and currval. 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
