Control/Force RTS Fabrication

There exists a fundamental issue whereby if a query predicate is > HIGH2KEY then the optimiser always estimates cardinality of 1.
For date/time related columns this is an issue as there may always be data beyond HIGH2KEY even immediately after runstats has just completed.
RTS Fabrication attempts to address this scenario but its dependency on also considering UDI% means that unless a significant proportion of new data is added/updated then RTS fabrication does not occur often enough to overcome this issue.
