conn.commit() is correct:

I used your code above and it worked, in that it created and populated
the tables and I could see the table and its contents in pgAdmin3.
So further questions:
1) Are you connecting to the same database in pgAdmin3 as in your Python
script?
2) In your previous post you say you cannot see the data, does that mean
you cannot see the table at all, or you can see the table but not the
data you inserted?
3) Remember Postgres folds upper cased names to lower case unless the
name is enclosed in double quotes. So in your example code above the
table gets created as company not COMPANY.
4) Have you used psql to look at the database to see if the table and
its data is there?
