[GRASSLIST:4992] Re: Interpolation of points in PostGIS database

[Bernhard Reimar Hoefle]

Hello again!

I can't use the PG driver in v.external. 

# ERROR: Cannot open data source

How can I install it? I'm using gdal-1.2.5 and GRASS 5.7.cvs
(grass57_exp_2004_11_27). I compiled it --with-postgres.
