DB Manager unable to show PostGIS geography column

[tjukanovt]

Describe the bug
DB Manager is unable to show the contents of a column of geography type from PostGIS

How to Reproduce

I imported a point layer to my local PostGIS (3.0, PG 11). I added a geography type column:
ALTER TABLE foo ADD COLUMN geog geography(POINT,4326);
I created points to that column based on the geometry column:

UPDATE foo
SET geog =
ST_GeogFromWKB(st_asewkb(geom))

But after this if I do a select statement, I can't see the geography columns or the contents. SELECT geog from foo returns nothing. In pgAdmin v4 the column works fine and it's also visible in the QGIS layer browser, but not in DB Manager.
