Prevent equal axis geometries with intersecting validity
Such things usually cannot happen via importing, but it is at least
consistent with constraints on other tables and the functionality
is needed for fairway dimensions, since they are first stored in the
staging area and equal geometries with intersecting validity could
be generated by a concurrent import.
Set the CONSTRAINT TRIGGER as INITIALLY DEFERRED because new entries
are inserted before the validity of existing entries is adapted
in the same transaction.
