Whenever I do a database migration that changes a table structure, I get a zillion of these errors: ActiveRecord::StatementInvalid: PGError: ERROR: cached plan must not change result type : SELECT "products".* FROM "products" WHERE "products"."id" = $1 LIMIT 1 The Rails processes throw the above exception until they are restarted. This screws up my zero-downtime deploys completely. I wonder if it would be possible for ActiveRecord to catch this exception and retry it? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
