Comment (by strk):

 I believe this is another effect of the same bug:
 {{{
 strk=# select geometrytype(tg) from public.com01012025_wgs84 limit 2;
  geometrytype
 --------------
  UNEXPECTED
  UNEXPECTED
 (2 rows)
 }}}

 Those TopoGeometry objects have feature_type=3 but I'm afraid the int64
 change made PostgreSQL read past the bounds of the actual data, as I
 anticipated in
