ALTER TABLE scans ADD COLUMN IF NOT EXISTS updated_at TIMESTAMPTZ DEFAULT NOW();

-- 2. Add missing columns to scan_results table if they don't exist

ALTER TABLE metric_values ADD COLUMN IF NOT EXISTS raw_value VARCHAR;

-- 7. Add missing columns to crawl_queue table if they don't exist
ALTER TABLE crawl_queue ADD COLUMN IF NOT EXISTS discovery_depth INTEGER DEFAULT 0;

CREATE INDEX IF NOT EXISTS idx_alerts_status ON alerts(status);
CREATE INDEX IF NOT EXISTS idx_crawl_queue_status_priority ON crawl_queue(status, priority);
CREATE INDEX IF NOT EXISTS idx_crawl_sessions_status ON crawl_sessions(status);

-- 10. Add RLS policies if they don't exist (basic ones)
-- Note: You may need to customize these based on your security requirements

-- Enable RLS on all tables
ALTER TABLE scans ENABLE ROW LEVEL SECURITY;
ALTER TABLE scan_results ENABLE ROW LEVEL SECURITY;
ALTER TABLE metric_values ENABLE ROW LEVEL SECURITY;
ALTER TABLE resource_analysis ENABLE ROW LEVEL SECURITY;
ALTER TABLE alert_configurations ENABLE ROW LEVEL SECURITY;
ALTER TABLE alerts ENABLE ROW LEVEL SECURITY;
ALTER TABLE crawl_queue ENABLE ROW LEVEL SECURITY;
ALTER TABLE crawl_sessions ENABLE ROW LEVEL SECURITY;

-- Basic RLS policies (you may want to customize these)
CREATE POLICY IF NOT EXISTS "Users can view scans for their organization" ON scans
    FOR SELECT USING (
        website_id IN (
            SELECT id FROM websites WHERE organization_id IN (
                SELECT organization_id FROM users WHERE id = auth.uid()
            )
        )
    );

CREATE POLICY IF NOT EXISTS "Users can insert scans for their organization" ON scans
    FOR INSERT WITH CHECK (
        website_id IN (
            SELECT id FROM websites WHERE organization_id IN (
                SELECT organization_id FROM users WHERE id = auth.uid()
            )
        )
    );

CREATE POLICY IF NOT EXISTS "Users can update scans for their organization" ON scans
    FOR UPDATE USING (
        website_id IN (
            SELECT id FROM websites WHERE organization_id IN (
                SELECT organization_id FROM users WHERE id = auth.uid()
            )
        )
    );

-- Similar policies for other tables...
-- (You may want to add more comprehensive RLS policies based on your needs)

-- 11. Refresh Supabase schema cache to pick up new columns
-- This is important to resolve "Could not find column in schema cache" errors
NOTIFY pgrst, 'reload schema';
