[ADMIN] How to read a sequence without incrementing it?

[Pierre Couderc]

I would like to read the current value of a sequence, or a value not too far of 
the current value (for example, the value it was a few seconds or minutes ago). 
Is it possible (without any nexrval that should increment it)?

Thank you all

Pierre Couderc
