Re: serial columns with replication/cluster

Sean,

take a look at UUID type. It might suit you better than serial.

Changing the increment also works, but puts a lot of restrictions on you
(such as planning to prevent collision, having to change the increment on
several nodes when adding a new node, etc.).
