Bug report #6510

PostGIS tables with both a Geometry and a TopoGeometry column

Added by Sandro Santilli about 8 years ago. Updated about 8 years ago.

Description

When a PostGIS table has both a geometry and a topogeometry column qgis only sees the geometry column.
To reproduce:

 CREATE TABLE t (g geometry, tg topogeometry);
 CREATE TABLE t2 (tg topogeometry);

Then "Add PostGIS layer", find the "t" table and you'll only see the "g" column, find the "t2" table and you'll see the "tg" column.
I've also tried to switch the order in which topogeometry and geometry columns are added but it's still only the geometry that gets considered when both are available.

May be related to #4532 but I'm not sure yet

History

#1 Updated by Sandro Santilli about 8 years ago

Note that if geometry_columns lookup fails (I temporarly renamed it for testing it) then both columns are shown.
It's a case of metadata lookup automatically becoming authoritative, triggering skipping of further lookup.
This is also when the "only check geometry_columns" option is unselected.

So yes I confirm it is related with #4532
