--- Comment #8 from Andrew Fuerste-Henry <andrew at bywatersolutions.com> ---
Confirmed that item search gives no results for number of checkouts=0 in 19.11.
However, in master I *do* get items with issues=null in item search results for
checkouts=0. So that search does work in master and I'm not sure what changed,
but this schema change seems worthwhile anyway.

To test:
- save and run this sql query in reports: select sum(if(issues is
null,1,0)),sum(if(issues=0,1,0)) from items
- you should see a lot of nulls and no zeros
- apply patch
- updatedatabase
- re-run your query and see that your nulls have changed to zeros
- create a new item
- rerun your query and see your new item is counted in the zeros, not the nulls
