[gdal-dev] FID in a vrt

[William Kyngesburye]

As I worked on a test case and fiddled around with a few other ideas, I think I found the error of my ways.

The computer I was doing the conversion from vrt to PostGIS has GDAL 1.8.  In my test case, GDAL 1.9 correctly preserves the FIDs.  Was -preserve_fid broken in 1.8?  I see the option listed in the help for 1.8, but not described (it is described in the 1.9 help).

But, neither version reports the FID column info on a vrt.  Though it does on the PostGIS table.
