What Philip is suggesting is to use Python only simple script to connect to database and retrieve from table. Something like:

import psycopg2

con = psycopg2.connect(<connection_str>)
cur = con.cursor()
cur.execute('select * from activitytypes')
rs = cur.fetchall()
print(rs)

Adrian,

con = psycopg2.connect(bustrac)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
NameError: name 'bustrac' is not defined

No this is because you did not use an actual connection string e.g:

psycopg2.connect("host=salmo user=rshepard dbname=bustrac")

Instead you used an undefined variable bustrac per the error message:

 NameError: name 'bustrac' is not defined

That's because there's a problem with connecting to the database. See my
reply to Rob's message.

Thanks,

Rich
