Got rid of some other notes as its only that annoying ST_Union(rast,uniontype) that's a sore in my back. git-svn-id: http://svn.osgeo.org/postgis/trunk@11082 b70326c6-7e19-0410-871a-916f4a2858ee --- diff --git a/doc/reference_raster.xml b/doc/reference_raster.xml index 600de5716..c5595f21c 100644 --- a/doc/reference_raster.xml +++ b/doc/reference_raster.xml @@ -10323,11 +10323,15 @@ UPDATE wind Description - Returns the union of a set of raster tiles into a single raster composed of at least one band.
