Giannis,
If your tile size is the same as the raster size, you're only going to
get one tile (and one row). Now if you were specify a tile size smaller
than the raster size (such as 30x31), you would have 117 tiles (and rows).
I wouldn't be concerned about not seeing the whole blob in pgAdmin.
pgAdmin usually does that for data that is particularly large.
