I have used TIGER (census) data with GRASS, and it can display street
maps (for that matter, you are supposed to be able to scan-in raster
maps and use a GRASS tool to calibrate them (click on three known points
on the map, and tell GRASS their coordinates)). I just wanted to make
it clear that GRASS will not tell you the street address, it will only
display a graphic of the street map with the desired point plotted (not
exactly what a 911 operator wants?)

With postgres, you must run 'initdb' to set-up the data directory (and
the postmaster CANNOT be started as 'root' (it will fail); you
traditionally start postgres as the user named 'postgres', who must also
own the database files):
mkdir /usr/local/pgsql/data
chown postgres /usr/local/pgsql/data
su -c "/usr/local/pgsql/bin/initdb -D/usr/local/pgsql/data" postgres
su -c "/usr/local/pgsql/bin/postmaster -D/usr/local/pgsql/data -i" postgres
To open 'psql' (the interactive SQL tool):
/usr/local/pgsql/bin/psql -Upostgres template1
Note that template1 is the default database. From inside psql, you
would want to create a new database to work with:
CREATE DATABASE utilpart;
\c utilpart
CREATE TABLE trucks (id serial, name text);
