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.</span></font>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">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: "</span></font><font color="navy"><span style="color: navy;">Random</span></font><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;"> </span></font>read is not supported by OGR for this
layer, cannot build support.<font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">" Then when I try to
display the created vector layer, GRASS crashes.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">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.</span></font></p>
