Hi,
I stored DEM raster data in PostGIS 2.0 and I used gdal_translate 
(with mode=2) to extract a mosaic of tiles. When I’m using GDAL 1.8 is 
working but when I’m using GDAL 1.9 I can see the values of pixel for 
just one tile. For example I uploaded in the database a tile with an 
attribute filename=056n05_w and an other tile with an filename=056n05_e 
and I executed the command with GDAL 1.8 and GDAL 1.9:
 
gdal_translate" -a_nodata "-32767" -of GTIFF  "PG:host=myhost 
port=14070 dbname='mybd' user='myuser' password='mypassword' 
schema='myschema'table='Elevation' mode=2 where=\"filename LIKE 
\'%056n05%\'\" " 056N05.tif
 
With GDAL 1.8 I obtained a mosaic of 2 tiles (the result expected) 
but with GDAL 1.9, I obtained a raster with the same extent but only the
 values of the tile 056n05_w are present. The pixels of the tile 
056n05_w have a value 0.
 
I tried the stable version 1.9 MSVC2008 (Win32) and development version available today  at  http://www.gisinternals.com/sdk/
 and I have still the same problem. For your information, I'm running 
GDAL on windows7 and PostGIS 2.0 is installed on a Linux server. I tried
 many version of GDAL 1.9 and I always have the same problem. The 
version 1.8 is working very well but I would like to take advantage of 
the improvements in the last version because I'm working on a project 
where processing time is very important.
 
Does anybody have any idea about this problem ?
 
Thanks
