Comment(by lucadelu):

 Replying to [ticket:2343 sbl]:
 > When running v.rast.stats on a dataset with small geometries (which in
 my case were represented by 2 pixels in the raster), the parameter
 "coeff_var" can result in "inf" value.
 > "inf" breaks the INSERT statement and results in an DBMI error "no such
 column: inf", which at the end crashes v.rast.stats.
 > Just like "nan", "inf" could be replaced by NULL. Changing line 263 in
 v.rast.stats.py into this:
 > if value.lower().endswith('nan') or value.lower().endswith('inf'):
 > should work.
 > Both GRASS 7.0 and 7.1 are affected. Please find attached patches for
 both versions...

 Could you provide a dataset to test the patches?
