[GRASS-de] Anzeigen von Postgis-Layern

[Michael Holzmann]

Beim schreiben eines Layers mit v.out.ogr in eine Postgis Datenbank wird
unter anderem auch die Spalte ogc_fid des Datentyps int4 angelegt.

"GRASS 5.7.cvs:~ > v.out.ogr input=fields type=area dsn="PG:dbname=testdb"
layer=felder format=PostgreSQL
 Exporting 65 areas...
 GRASS Topology -> Simple Features conversion (may take some time)...
 Processing area 65... 100%
 67 features written
 WARNING: 2 features without category written"

Das Einbinden des Layers mit v.external funktioniert auch noch wie unten zu
sehen ist.

"GRASS 5.7.cvs:~ > v.external dsn="PG:dbname=testdb" layer=felder
output=Felder
 Building topology ...
 Feature:   67
 Topology was built.
 Number of nodes     :   130
 Number of primitives:   154
 Number of points    :   0
 Number of lines     :   0
 Number of boundaries:   87
 Number of centroids :   67
 Number of areas     :   87
 Number of isles     :   87
 Number of areas without centroid :   20"

Wenn ich dann den Layer anzeigen lassen will kommt folgende Nachricht:

"GRASS 5.7.cvs:~ > d.vect map=Felder
 ERROR: Cannot read feature, FID = 0

    (procedure "Button::_release" line 18)
    invoked from within
 "Button::_release .mainframe.topf.tb0.bbox1.b0"
    (command bound to event)

Auch wenn ich die Spalte umbenenne in fid funktioniert es nicht

gearbeitet wird mit:
-grass5.7.cvs-i686-pc-linux-gnu-26_06_2004
-Postgresql 7.4.2
-Postgis 0.8.1
-gdal 1.1.9

Für Hilfe wäre ich sehr dankbar
