Etienne,

What does the "it doesn't work" exactly mean?

The SetSRID is definitely implementing for raster and writes new SRID to
raster header (the canonical WKB stream):
http://trac.osgeo.org/postgis/browser/trunk/raster/rt_pg/rt_pg.c#L700

UpdateGeometrySrid is geometry-only function, does not work for rasters.

Best regards,
Mateusz
