Can you file a ticket for this? Make sure to include your example. It
looks like something is wrong in GDAL's GDALFPolygonize() function.

ST_DumpAsPolygons() is special as that calls a GDAL function while
ST_PixelAsPolyons() is completely internal to PostGIS. I'll do some digging.

Bborie,
I used ST_Value to prove that the value for pixel with coordinates (8,2)
does exist. I did not mention it but adjacent pixels contains different
values (see reproducible example).

ST_Value and ST_DumpAsPolygons do very different things. ST_Value gets a
value for a specific pixel while ST_DumpAsPolygons() dumps values by
merging pixels with same value in an area.

Dear List,
value's number 4 in this raster come out with ST_Value:
SELECT ST_Value(rast, 1, 8, 2), ST_BandnoDataValue(rast),
ST_BandPixelType(rast)
