Uh, logically, yes, but practially currval just reads/SELECTs, while nextval modifies/UPDATEs. > Considering there's no currval() without nextval(), what point > is disallowing currval() when user is able to call nextval()?

We could easily have INSERT control that if we wanted, but I think you have to make a clear use case to override the risk of breaking applications. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(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
