I have a table with a few invalid geometries (empty rings, self-intersections). I'd like to fix them up something like this:

```
update mytable
set geomcolumn = st_makevalid(geomcolumn)
where id = 123;

```

and I get "**ERROR: Geometry type (GeometryCollection) does not match column type (MultiPolygon)"**

is there some other function I need to wrap the st\_makevalid() in to get a compatible type, or something else?
