-- This migration is closely related to '01recreate_stream_ordering.sql.postgres'. | ||
-- | ||
-- It updates the other tables which use an INTEGER to refer to a stream ordering. | ||
-- These tables are all small enough that a re-create is tractable. | ||
ALTER TABLE pushers ALTER COLUMN last_stream_ordering SET DATA TYPE BIGINT; | ||
ALTER TABLE federation_stream_position ALTER COLUMN stream_id SET DATA TYPE BIGINT; | ||
|
||
-- these aren't actually event stream orderings, but they are numbers where 2 billion | ||
-- is a bit limiting, application_services_state is tiny, and I don't want to ever have | ||
-- to do this again. | ||
ALTER TABLE application_services_state ALTER COLUMN last_txn SET DATA TYPE BIGINT; | ||
ALTER TABLE application_services_state ALTER COLUMN read_receipt_stream_id SET DATA TYPE BIGINT; | ||
