-- Migration 086: Add proxy_url column for alternative URL formats
-- Some proxy providers use non-standard URL formats (e.g., host:port:user:pass)
-- This column allows storing the raw URL directly

-- Add proxy_url column - if set, used directly instead of constructing from parts
ALTER TABLE proxies
ADD COLUMN IF NOT EXISTS proxy_url TEXT;

-- Add comment
COMMENT ON COLUMN proxies.proxy_url IS 'Raw proxy URL (if provider uses non-standard format). Takes precedence over constructed URL from host/port/user/pass.';
