[postgis-users] Trying to import natural earth data into

[David Blackman]

what's v.clean? It seemed for me that just v.ogr.in + v.ogr.out fixed
all my natural earth errors

out of curiosity, why not include admin-1-provinces too? Having
state-level data seems  to be one of the biggest differentiators of
the data set over most other public data sets.
