Alliums. Plants in the Allium family, such as the dramatic Allium giganteum whose flower heads adorn stalks up to 6 feet tall, are regarded as a broad-spectrum natural insecticide. They repel numerous insects that plague vegetable gardens, including slugs, aphids, carrot flies and cabbage worms. Plants that will benefit from the proximity of alliums include tomatoes, peppers, potatoes, cabbage, broccoli, kohlrabi and carrots. They also will keep aphids off rose bushes.
A Login grants the principal entry into the SERVER. A User grants a login entry into a single DATABASE. Logins are a server wide (instance level) objects. Their correct name is 'server principals' (see sys.server_principals). Server wide privileges are granted to logins, like create database or view server state permissions.
Use www-data. There is a difference between the database user and the Apache user. The Apache User is the only one who can actually read the files. The database user is only meant for giving/taking database read/write permissions. In addition, keep the default permissions from the webapp install.
