Package: thuban
Version: 1.0.0-1
Severity: important
When trying to select a postgis source using thuban, it fail to list
the column in the table. This is a problem when one table contain
several geometry columns. It would be better if the table list
included the name of the geometry column as well.
I create this table:
CREATE TABLE postal_codes (
postal_code text NOT NULL PRIMARY KEY,
postal_location text
);
SELECT AddGeometryColumn('','postal_codes','center_point', '-1','POINT', 2);
SELECT AddGeometryColumn('','postal_codes','area', '-1','POLYGON', 2);
I select "File->Database Connections" to enter the database connection
info. Next, I visit "Map->Add Database Layer", select the database
and press "Retrieve". This make my list of postgis sources appear
under "Tables", but this table appear as two entries with
"postal_codes" as the name. There is no way to know which is which of
these.
I then try to select one of these, and press "OK", I get this crash
backtrace:

I'm not sure if the crash is related to the problem with the two
tables listed without any qualifier.
