Description
Apparently in DB Manager I can create a view like
CREATE VIEW test_view AS
SELECT a.gid AS gid, a.descricao, ST_Intersection(a.geom,b.geom)::geometry(LineString,3763) AS geom
FROM training.rede_ferroviaria a, training.evora b
WHERE ST_Intersects(a.geom, b.geom);
without errors.
If the same query is done to create a table it would give
Geometry type (MultiLineString) does not match column type (LineString)
So... if afterwards I open the "table" or "preview" tab of the created view, DB Manager will give first

attached. Import both vectors in PostGIS then run the query is
CREATE VIEW test_view AS
SELECT a.gid AS gid, a.descricao, ST_Intersection(a.geom,b.geom)::geometry(LineString,3763) AS geom
FROM rede_ferroviaria a, evora b
WHERE ST_Intersects(a.geom, b.geom);

Not reproducable - the query fails, the "Database Error" window with the error message pops up, Table and Preview tabs are empty. Changing to an other layer and back doesn't reproduce the error, unless the tree is refreshed.

seems that in the meantime somehow the issue was fixed.
