-- On SQLite we must be in monolith mode and updating the database from Synapse,
|
|
-- so its safe to assume that `event_push_actions_staging` should be empty (as
|
|
-- over restart an event must either have been fully persisted or we'll
|
|
-- recalculate the push actions)
|
|
DELETE FROM event_push_actions_staging;
|
|
|
|
-- Add a column so that we know when a push action was inserted, to make it
|
|
-- easier to clear out old ones.

ALTER TABLE event_push_actions_staging ADD COLUMN inserted_ts BIGINT;
