Comment(by dustymugs):

 I'm going to have to find a resolution for the snprintf issue ASAP as I
 use that function quite a bit.

 ST_AsGDALRaster is a generic interface to creating an GDAL raster.  Thus,
 it does no format-specific checking unlike ST_AsTIFF, ST_AsJPEG and
 ST_AsPNG.  So, if you pass a multiband raster to ST_AsGDALRaster, the
 function will try to add all the bands to the GDAL raster.

 Therefore, most users should use ST_AsTIFF, ST_AsJPEG and ST_AsPNG.  Those
 users who don't need hand-holding (basically have read the appropriate
 GDAL format page) should be able to do everything that GDAL raster output

 Also, my development environment is on PostgreSQL 9.0.4.  PostGIS output

 "POSTGIS="2.0.0SVN" GEOS="3.2.2-CAPI-1.6.2" PROJ="Rel. 4.7.1, 23 September
 2009" LIBXML="2.7.6" USE_STATS"

 All have been built using GCC 4.4.4 running on Slackware 13.1.
