Seems that what you have here is a bad manual implementation of a sequence. Why don't you use a real sequence object and nextval()?
Well, if I use the real sequence, I'll need unpredictable number of them and will have to store mapping (section, name)->sequenceName, and also will have to create those sequences dynamically the similar way.
