I don't want to beat a dead horse, and I know that this has been covered
to a degree on this list before, but is there any way to speed up the
export of a large vector layer (points in this case) to a shapefile? I
have 750,000 points and it looks like it will take a few hours to export.
This is with the attribute data stored in a PostgreSQL database.
I did build an index on the category field in the database, and I think it
helped to a degree, but I can't be certain that GRASS is even using the
index.
