Hello,

I'm trying to run this application (https://github.com/ilvalle/w2pgis) and I'm getting the following problem:

First time I've tried to execute, I got the following error:

               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

I'm using the following code:

# -*- coding: utf-8 -*-
db = DAL('postgres://web2py:web2py@localhost:5432/leaflet', lazy_tables=False)

db.define_table('geostuff',
    Field('name', 'string'),
    Field('geometry', 'geometry()'),
)


n_rows = db(db.geostuff).count()
if not n_rows:
    db.geostuff.insert(name="My first geo point (London!)", geometry="POINT(-0.091109 51.512622)")
    db.geostuff.insert(name="My first linestring", geometry="LINESTRING (8.791595 45.660281, 11.343062 44.494932, 10.394590 43.722998)")

Could you help me please?

Ty.
