#3512: ST_DumpAsPolygons documentation confusing wrt no data value
---------------------------+---------------------------
 Reporter:  strk           |      Owner:  robe
     Type:  defect         |     Status:  new
 Priority:  medium         |  Milestone:  PostGIS 2.2.3
Component:  documentation  |    Version:  2.2.x
 Keywords:  raster         |
---------------------------+---------------------------
 The ST_DumpAsPolygons documentation contains a NOTE mentioning that pixels
 with nodata value would not be returned, but there's a parameter that can
 change such behavior, so the documentation is confusing in that reguard.
