ST-2.1: Unify timeframe enum - Created ddl/00-global-types.sql with public.trading_timeframe - Marked trading.timeframe and market_data.timeframe as DEPRECATED ST-2.2: Resolve transaction_type conflict - Documented rename plan: financial.wallet_transaction_type - Documented rename plan: investment.investment_transaction_type - Added deprecation comments to both enums ST-2.3: Unify common functions - Created ddl/00-global-functions.sql with public.update_updated_at() - Marked schema-specific functions as DEPRECATED: - auth.update_updated_at() - education.update_updated_at_column() - financial.update_timestamp() - feature_flags.update_timestamp() Migrations created (not executed): - 2026-02-03_unify_timeframe_enum.sql - 2026-02-03_rename_transaction_type_enums.sql - 2026-02-03_unify_common_functions.sql Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

-- Migration: Unify timeframe enum across schemas
|
|
-- Date: 2026-02-03
|
|
-- Task: ST-2.1
|
|
-- Issue: DUP-001 - timeframe enum duplicated in trading and market_data
|
|
-- ============================================================================
|
|
--
|
|
-- SUMMARY:
|
|
-- This migration creates a unified timeframe enum in the public schema.
|
|
-- The enum is a superset of all values from:
|
|
-- - trading.timeframe: '1m', '5m', '15m', '30m', '1h', '4h', '1d', '1w', '1M'
|
|
-- - market_data.timeframe: '1m', '5m', '15m', '30m', '1h', '4h', '1d', '1w'
|
|
--
|
|
-- DIFFERENCE IDENTIFIED:
|
|
-- - trading.timeframe has '1M' (1 month)
|
|
-- - market_data.timeframe does NOT have '1M'
|
|
-- - Unified type includes ALL values (superset)
|
|
--
|
|
-- ============================================================================
|
|
|
|
-- Step 1: Create unified enum in public schema (superset of all values)
|
|
DO $$
|
|
BEGIN
|
|
IF NOT EXISTS (
|
|
SELECT 1 FROM pg_type
|
|
WHERE typname = 'trading_timeframe'
|
|
AND typnamespace = (SELECT oid FROM pg_namespace WHERE nspname = 'public')
|
|
) THEN
|
|
CREATE TYPE public.trading_timeframe AS ENUM (
|
|
'1m', '5m', '15m', '30m', '1h', '4h', '1d', '1w', '1M'
|
|
);
|
|
END IF;
|
|
END $$;
|
|
|
|
COMMENT ON TYPE public.trading_timeframe IS 'Unified timeframe enum for all trading-related tables. Replaces trading.timeframe and market_data.timeframe';
|
|
|
|
-- ============================================================================
|
|
-- Step 2: Migration plan for existing tables (NOT EXECUTED - requires planning)
|
|
-- ============================================================================
|
|
--
|
|
-- AFFECTED TABLES (to be migrated in future):
|
|
--
|
|
-- Schema: trading
|
|
-- - trading.trading_signals (column: timeframe)
|
|
-- - trading.bot_configurations (column: timeframes - array)
|
|
-- - Any other tables using trading.timeframe
|
|
--
|
|
-- Schema: market_data
|
|
-- - market_data.ohlcv_data (column: timeframe)
|
|
-- - market_data.symbols (column: supported_timeframes - array)
|
|
-- - Any other tables using market_data.timeframe
|
|
--
|
|
-- MIGRATION STEPS FOR EACH TABLE:
|
|
--
|
|
-- a) Add new column with public.trading_timeframe type:
|
|
-- ALTER TABLE schema.table ADD COLUMN timeframe_new public.trading_timeframe;
|
|
--
|
|
-- b) Copy data from old column:
|
|
-- UPDATE schema.table SET timeframe_new = timeframe::text::public.trading_timeframe;
|
|
--
|
|
-- c) Drop old column and rename new:
|
|
-- ALTER TABLE schema.table DROP COLUMN timeframe;
|
|
-- ALTER TABLE schema.table RENAME COLUMN timeframe_new TO timeframe;
|
|
--
|
|
-- d) After all tables migrated, drop schema-specific enum:
|
|
-- DROP TYPE trading.timeframe;
|
|
-- DROP TYPE market_data.timeframe;
|
|
--
|
|
-- WARNING: This is a breaking change that requires:
|
|
-- 1. Backend code updates to use new type
|
|
-- 2. Application downtime or blue-green deployment
|
|
-- 3. Careful coordination with all services
