"Depending on the type of object, the initial default privileges might
include granting some privileges to PUBLIC. The default is ... CONNECT
privilege and TEMP table creation privilege for databases"
http://www.postgresql.org/docs/8.3/interactive
/ddl-schemas.html#DDL-SCHEMAS-PUBLIC
Note that by default, everyone has CREATE and USAGE privileges on the schema
public. This allows all users that are able to connect to a given database
to create objects in its public schema. If you do not want to allow that,
you can revoke that privilege:
REVOKE CREATE ON SCHEMA public FROM PUBLIC;
