-- 202_fix_admin_create_stop.sql
-- Fix/recreate admin_create_stop RPC using the signature required by callers.
--
-- The previous migration 147 defined the function but was never applied (or
-- was lost) to the live DB, resulting in PGRST202 "function not found" when
-- "Add New Stop" (createStop server action) tries to call it.
--
-- This uses the parameter order from the reported error + best-practice
-- style (always return jsonb with success/stop_id or error; no RAISE).
-- Robust date/cutoff parsing and slug generation are preserved so that
-- required columns (slug, status) are populated and duplicates are avoided.
--
-- Matches the client call in src/actions/stops/create-stop.ts which passes:
--   p_brand_id, p_city, p_state, p_location, p_date, p_time,
--   p_address, p_zip, p_cutoff_time, p_active
-- (named keys; param order in CREATE only affects the GRANT signature).

BEGIN;

-- Drop any stale overloads that might confuse PostgREST cache or signature matching.
