Hi all,

how to fix a problem, suppose there is a table with id and username

if I set the id to bigint so the limit is 9223372036854775807 
if I insert for example 3 rows
id    username
--    --------------
1     abc
2     def
3     ghi

if I delete all rows and insert one another it is like

id    username
--    --------------
4     jkl


So it doesn't start again from non-available id 1, so what is needed to do to make the new inserts go into non-available id numbers?

and if the id reaches the limit and maybe there is some ids that are not used.
