Note that in the days of virtual machines, those more or less "invent" their MACs. Since they just have to be unique in the subnet (or "broadcast domain"), collisions on a more global scale will go unnoticed. But they might bite you in a replicated database scenario.

Re: [BUGS] BUG #4274: uuid returns duplicate values
Hi Testing on my home system, looking good... will try on my office system Monday. Note: I am assuming that the uuid will mostly be used as a primary key on records that will exist in replicated databases to guarantee uniqueness. The problem that is see with the current uuid functions for this purpose is that the generated uuid is very random causing great performance issues with the index; at least when using oracle and ms sql server, did not try with postgres, but must be similar. Usually inserting random data into an index of any kind is a worst case stress test. Hence the older style of uuid, based on mac addresses and time tend to generate more sequential uuid's, at least when inserting a bunch of records at once. In other words it would be nice to have the old fashioned style of uuid's.

Re: [BUGS] BUG #4274: uuid returns duplicate values
Hi I just tried it, slightly better but not a runner Here is a sample of the results I get when running my test script, note result vary but lack of duplicates does not. Why do you not use the CreateUUID function in windows??
