Hi list !
Do you know what happen with the tutorial about using postgrass driver to store vectors within postgis ? There is many references to http://grass.itc.it/grass57/tutorial/geom_storage.html#PostGRASS in documentation but the section doesn't exist anymore.
In fact, it exists always but have been commented (!?) So you can read the section in page source code...
Any explanations ?
Greetings,

Hi Jean-Denis,
I have added this note on top of the old tutorial:
NOTE: This tutorial is refering to GRASS 5.7. Meanwhile (2005), GRASS 6.0.0
has been published. An updated (but unfortunately still incomplete) version
of this tutorial is available here: GRASS Six Tutorial.
http://grass.gdf-hannover.de/twiki/bin/view/GRASS/GrassSixTutorial
I still have to migrate parts of the old tutorial into the Wiki.
Answering your question: The direct PostGIS connection is no
longer available. Once day, when OGR comes with a GRASS plugin
for vector data, this will probably change.
For now you can use v.in.ogr and v.out.ogr to directly exchange
data with PostGIS. But it's an exchange, no real link into the DB.
Hope this helps
Markus

It is possible to make the 'link' to any OGR layer (i.e. also PostGIS) with v.external, but attributes with PostGIS work only if FID exists.

right, but it's a read-only connection with v.external then.

Thanks for your answer !
It's quite sad because I saw the use of PostGRASS as a great way to
offer advanced spatial analysis within a Web portal using GRASS +
PostGIS + Mapserver.
Maybe the 6.x serie will offer interesting alternative !

Someone will have to write an OGR/GRASS plugin for vector data
or port the QGIS vector interface (not sure, probably the architecture
is totally different).
Let's hope the best
