Re: Moving from MySQL to PGSQL....some questions

Uh, which behaviour do you want? The one Scott just got, or the one you
claimed to get earlier (which is not the same as what Scott got). I'm not
sure how you can do on MySQL what you claimed to get on MySQL with just the
autoincrement feature.

Do you require a contiguous sequence of numbers - no skipped numbers, or
ascending unique numbers will do?
