[GRASS-dev] v.out.ogr: speed up

[Martin Landa]

Hi,

I have added OGR transactions support to v.out.ogr to speed up export
to OGR datasources which supports transactions.

Using `geodetic_pts` from `nc_spm_08` (~30k points), exporting to PostGIS

$ time v.out.ogr dsn=PG:dbname=pgis_grass input=geodetic_pts
format=PostgreSQL type=point --o

Before:

real    4m37.795s
user    0m8.201s
sys     0m4.752s

After (r45912):

real    0m11.499s
user    0m3.856s
sys     0m1.728s

Available in GRASS 6.5+, backport marked for 6.4.2. Testing welcomed.

Martin
