make converting to multi geometries to fullfil provider geometry
constraints the last step and use earlier conversions (fixes #17643)

This is specific to PostGIS only.

I can confirm. it creates NULL geometries. i think it depends on the geometrytypewhich is defined in the postgis table. with MULTIPOLYGON this problem occurs in my case.

CREATE TABLE public.gis_gruen_f
geo_id integer NOT NULL DEFAULT 0,
the_geom geometry(MultiPolygon,31467) NOT NULL DEFAULT NULL::geometry,
CONSTRAINT pk_gis_gruen_f PRIMARY KEY (gid),
CONSTRAINT enforce_dims_the_geom CHECK (st_ndims(the_geom) = 2),
CONSTRAINT enforce_geotype_the_geom CHECK (geometrytype(the_geom) = 'MULTIPOLYGON'::text OR the_geom IS NULL),
CONSTRAINT enforce_srid_the_geom CHECK (st_srid(the_geom) = 31467)

with other dataprovider this problem do not occur. after click save edits, the circular/curved geometry converted/segmentized to the defined geometrytype in the datasource.

its possible to set the priority of this issue to "high". i think its an important issue for digitizing.

thank you

QGIS 2.18.x and actual master are affected

it's possible that anybody of the fantastic qgis developers could solve this problem for qgis 3.0 release?

@Jürgen Fischer
It's easy to fix that issue?
