-- This script is used to completely reset the public schema by dropping all tables.
-- It should be run before re-running the master schema script to ensure a clean state.
-- The CASCADE option is used to automatically handle dependent objects like foreign keys.
-- The order is grouped logically for readability, though CASCADE makes the exact order less critical.

-- Drop PostGIS System Tables (Optional)

-- These tables are created by the PostGIS extension. Dropping them ensures
-- a completely clean public schema if the extension were to be re-installed.
-- It's generally safe to include these in a full reset script.

-- These tables are owned by the 'postgis' extension and cannot be dropped directly.
-- Doing so would require dropping the extension itself, which is not the goal of this script.
-- We only want to reset the application's data, not the database's extensions.
