Hi, GRASS users! I am a novice, and have only been using this program
for a couple of months now. I'm having a problem using GRASS with
postgres for a project at work, and I was wondering if you guys could help.
I'm working with shapefiles, and want to display them in GRASS. Some of
these files are large enough to crash GRASS while cleaning, and even
more take longer to draw and redraw than I'd like. To avoid this, I'm
attempting to use v.external to connect to the files in a postGIS table,
created using shp2pgsql. When I run v.external, however, I get a strange
warning: "Random read is not supported by OGR for this layer, cannot
build support." Then when I try to display the created vector layer,
GRASS crashes.
Spencer,
On review of the OGR PostGIS driver I think this is a bug in the driver's
"TestCapabilities" method. Are you in a position to rebuild your GDAL with
a patch? I'd appreciate your filing a bug against GDAL/OGR for this issue,
and we can pursue the discussion there.
