[postgis-users] RE Importing shapefiles to PostGIS

[Shreerang Patwardhan]

Hello all,
        I have followed the following steps to import TIGER shapefile to
PostGIS . I  got the following output and errors.

shreerang at ubuntu:~/Shapefiles/
06001_Alameda_County/tl_2008_06001_arealm$ shp2pgsql -s 4326 -I -S
tl_2008_06001_arealm.shp public.test_db > tl_2008_06001_arealm.sql
Shapefile type: Polygon
Postgis type: POLYGON[2]

shreerang at ubuntu:~/Shapefiles/06001_Alameda_County/tl_2008_06001_arealm$
psql -d test_db -U postgres -f import.sql
psql: FATAL:  Ident authentication failed for user "postgres"


Now, I followed the following procedure. I wish to know if it is right or
wrong.

The first command is as it is....
For the next one,

shreerang at ubuntu:~/Shapefiles/06001_Alameda_County/tl_2008_06001_arealm$
sudo su postgres
[sudo] password for shreerang:
$ psql -U postgres
could not change directory to
"/home/shreerang/Shapefiles/06001_Alameda_County/tl_2008_06001_arealm"
Welcome to psql 8.3.9, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

postgres=# psql -d test_db -U postgres -f import.sql

Is this right?
And what should the output look like if this is right?...

Need help!!!


Thanx,
Shreerang.
