Maybe someone using GRASS 5.3 or 5.4 can provide it.

thank you
I think in grass6 raster to vector does what r.to.pg does internally.
as:
Column | Type | Modifiers
--------+-----------------------+------------------------------------
cat | integer |
value | integer |
label | character varying(95) |

Hi,
right! you can convert the raster map into vector format and write all
attributes into PostgreSQL. But there is a difference: r.to.pg writes each
pixel value to the table, r.to.vect writes feature (points, lines, polygones)
attributes.
I guess, it depends on what you want to do. Some years ago, I needed raster
pixel values to be able to calculate statistics with R from PostgreSQL table
entries -> that's why r.to.pg was necessary and useful to me.
best wishes
Otto
