And I think that "care about gaps -> sequence doesn't work" is a knee-jerk reaction. It's similar to "can't parse HTML with regexps". 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.
