I'm sure most of you are familiar with at least one flavor of Unix, so
I'm sure I'm not going to leave anyone confused. (I hope.)
Why not maintain a sequence, but allow implicit UID assignment? ie;
CREATE USER user --UID1;
CREATE USER user2 WITH UID 2; --UID2
DROP USER user2 --buhbye;
CREATE user2 --Now gets UID3;
CREATE user3 WITH UID2 --user3 now has UID2;
Default behaviour being if a UID has -been- used (not is -in- use) that
it continues on?
