Peter Eisentraut 1772d554b0 Fix NO ACTION temporal foreign keys when the referenced endpoints change 
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.
