 Configured correctly, Django SQL Dashboard uses a number of measures to keep your data and your database server safe:
 
-- I strongly recommend creating a dedicated PostgreSQL role for accessing your database with read-only permissions granted to an allow-list of tables. PostgreSQL has extremely robust, well tested permissions which this tool can take dull advantage of.
