True in the general case, and therefore people tend to blurt it out
every time the topic comes up. But not necessarily true in specific
cases. As I wrote above, there is no perfect solution - so you have to
think about the actual requirements and the consequences of various
solutions - and maybe using a sequence is the best (or least bad)
solution.
OK. In that case, I will proceed with the millions of sequences. We will see.
Anyway, It will be awesome if we have a sequence data type in a future version of postgresql. They will solve a lot of problems similar to this one.
