[gdal-dev] gdalinfo on PostGIS rasters (GDAL 1.9)

[Mathieu Basille]

Dear Even,

This works now perfectly!

I didn't have time to install GDAL trunk until now. The installation went 
almost smoothly (see below if it is any useful). If I run the exact same 
gdalinfo command as before , I now have relevant information:

$ gdalinfo "PG:dbname=mydb host=localhost user=pguser schema=myschema 
table=myraster"
Driver: PostGISRaster/PostGIS Raster driver
Files: none associated
Size is 12, 11
Coordinate System is:

This is perfect! Thanks a lot.
