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. In the GRASS documentation, it mentions adding a unique ID column to the postgres table, but with or without the column the same warning occurs, and the program still crashes. I'm kinda stumped for what to do next, and so I turn to you all for advice. Have you received this warning/crash yourselves, and if so, how was it resolved? Thank you very much. -- -Spencer Fogg
