If a referenced UPDATE changes the temporal start/end times, shrinking the span the row is valid, we get a false return from ri_Check_Pk_Match(), but overlapping references may still be valid, if their reference didn't overlap with the removed span. We need to consider what span(s) are still provided in the referenced table. Instead of returning that from ri_Check_Pk_Match(), we can just look it up in the main SQL query.
