And it may be the latter.  On closer review I think some adjustment
may be needed in IndexBuildHeapRangeScan().  I'm not sure that
throwing the error is necessary, since there is a flag to say that
the index is unsafe for existing snapshots -- it may be enough to
set that flag.

Sorry for my earlier email.
