I am using PostGIS 2.0 and I want to use the raster functionality through mapserver. It seems as if the latest official GDAL release 1.9.1 has an unstable PostGIS raster driver, as pointed out in a previous question. After posting a ticket, was advised on github to update GDAL from trunk for this to work. I did that but I still get the same error. Thus, my question is:
Is it necessary to build PostGIS again from source after updating GDAL for that update to become effective in PostGIS?
