                          In PostgreSQL there is a field called allowedMode called SFRM_Materialize_Random

> The Tuplestore must be created with randomAccess = true if
SFRM_Materialize_Random is set in allowedModes, but it can (and preferably
should) be created with randomAccess = false if not.

In which case is this set?
