The following query excludes anything with site_license null or {}, due to how sql works:
select site_license from projects where state#>>'{state}' in ('running', 'starting') and site_license!='{}';
We then just process the result in Javascript. It would be possible to make a more complicated query that
does all the processing in the database, and returns less data as output, but that would be harder for me,
so I leave that to others or later (since this query is not likely to be used too much).
