[Bug]: Potential Duplicate ReportIDs possible

[userjack6880]

Per Issue #112 on the pre-fork version, it's been pointed out that Duplicate ReportIDs are possible. It is possible to fix, and a solution is provided, though the implementation is not quite what we need. Adapt the solution to this project and include a check to automatically update the index in both Maria and PostgreSQL (index checks would be different for the two versions). Perhaps introduce an update script instead?
