Isto nao faça conexões python dentro do gluon ela ja existe. voce tem que
fazer no models de cada aplicação.
ex: web2py\aplications\minhaapp1\model\db.py
import psycopg2
db = DAL('sqlite://storage.db')
db = DAL(' postgres://username:password@localhost/test')
Para cada aplicação uma conexao ou varias conexões se voce mexer na conexao
com o Gluon vc vai estar alterando a conexao global e nao a conexão para
cada aplicação em particular.
