[gdal-dev] ogr2ogr changes field length

[Even Rouault]

Matteo,

When overwriting, a fresh new file/table is creating, without keeping 
anything from the existing version.

You could probably just blank your target with

ogrinfo target.shp -sql "DELETE FROM target" -dialect SQLITE

and then ogr2ogr -append target.shp PG:....   -nln target
