title: Integer values allocation
body: <p>I have a table that generates integer values (currently on <code>10,230</code>) and I have this list of accounts which I want to assign these integer values to but will not be used in prod yet.</p>
  
  <p>I want to allocate 20 of the next values, (e.g. <code>10,231</code>, <code>10,232</code>, etc.) but what I want is for the next person that will make an insert into the prod table to not take those values which I allocate for those accounts. How can I prevent those values from being assigned to someone else?</p>
  
  <p>Basically, I want people to start generating values from <code>10,251</code> onward as <code>10,230</code> - <code>10,250</code> are allocated by me.</p>
