Someone (a manager) somewhere (probably marketing) sometime (when you least expect it) will demand that those short text names be changed, possibly for a completely irrational reason. I know there are still text books that claim that artificial keys are evil for some inscrutable reason, but hard experience has taught me to never, ever, under any circumstance, make a primary key out of data that comes from humans, and to be very suspicious of using data that will be visible to humans. -- Scott Ribe scott_ribe@xxxxxxxxxxxxxxx http://www.killerbytes.com/ (303) 665-7007 voice ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
