How to import shp files into postgresql with PostGIS?

Question

I'm a new user of postgreSQL/postgis but I'm having a problem.

I'm trying to import some shapefiles (which open perfectly in QGIS or ArcGIS but create an error when i import them). The problem is not because it's in a directory with accents (that was my first problem).

When loading the data, I get this message :

> Importing with configuration: nyc_neighborhoods, public, geom,
> C:\Users\Lay\Desktop\NYC\nyc_neighborhoods, mode=c, dump=1, simple=0,

It's in french though I installed postgis in english to avoid this problem. It says that there is no specific function associated and given to the different types of arguments and that i have to add specific conversions. However, I do not really get what this error means or how I can solve it. I hope some off you know!!

Thanks!

Answer 1

Using google translate, the message you are getting appears to be :

No function matches the given name and argument types

I suspect you do not have PostGIS installed, or enabled on the database you are trying to import data to. The AddGeometryColumn function comes with PostGIS (which is an extension to postgresql).

Try to execute legacy.sql for your database.

On unix you can do that by running

psql my_postgis_db -f <installdir>/postgresql/share/contrib/postgis-2.0/legacy.sql

For windows I think you can use pgAdmin if I am not mistaken. Search your installation directory for legacy.sql . It should be somewhere there.
