Comment (by andehhh):

 I found the upgrade error. I upgraded my main database but not the one I
 used for testing. Here is now the correct output from
 `postgis_full_version()`:

 `POSTGIS="2.3.2 r15302" GEOS="3.5.0-CAPI-1.9.0 r4084" PROJ="Rel. 4.9.2, 08
 September 2015" GDAL="GDAL 1.11.3, released 2015/09/16" LIBXML="2.9.3"
 LIBJSON="0.11.99" TOPOLOGY RASTER`

 The error prevails.

 Which debugging would I have to enable to see those geometry constructions
 in detail? Changing `log_min_messages` to `DEBUG5` would only log the
 error message and the statement but nothing more detailed.
