-- Drop legacy cache token columns that lack the underscore separator.
|
|
-- These were created by GORM's automatic snake_case conversion:
|
|
-- CacheCreation5mTokens → cache_creation5m_tokens (incorrect)
|
|
-- CacheCreation1hTokens → cache_creation1h_tokens (incorrect)
|
|
--
|
|
-- The canonical columns are:
|
|
-- cache_creation_5m_tokens (defined in 001_init.sql)
|
|
-- cache_creation_1h_tokens (defined in 001_init.sql)
|
|
--
|
|
-- Migration 009 already copied data from legacy → canonical columns.
|
|
-- But upgraded instances may still have post-009 writes in legacy columns.
|
|
-- Backfill once more before dropping to prevent data loss.
