    265265 This is a set-returning function (SRF). A "geomval" value is a complex type composed of a polygon geometry (one for each group of pixel sharing the same value) and the value associated with this geometry. These values are always returned as a value of type double precision. The shape of each polygon follow pixels edges.
    266266
    267  Variant 1: ST_AsPolygon(raster) -> geomval set -- default to band # 1
    268  Variant 2: ST_AsPolygon(raster, integer, 'UNGROUP')
     267 Variant 1: ST_AsPolygon(raster) -> geomval set -- default to band # 1[[BR]]
     268 Variant 2: ST_AsPolygon(raster, integer, 'UNGROUP')[[BR]]
    269269 Variant 3: ST_AsPolygon(raster, 'UNGROUP') -- default to band # 1
