Hi

We're considering upgrading from Firebird 2.0 to 2.1 and a main
motivation for this is to use Global Temporary Tables.

Each instance of GTT is generated when it's first referenced therefore
there will be no data in it so the index statistics will always be 0.
Will this upset the optimiser or Firebird treats GTT differently?
Should we manually set statistics after we populate some data into GTT's?

Thanks
Huan
