-- Store the number of unread messages, i.e. messages that triggered either a notify
-- action or a mark_unread one.
ALTER TABLE event_push_summary ADD COLUMN unread_count BIGINT NOT NULL DEFAULT 0;
-- Pre-populate the new column with the count of pending notifications.
-- We expect event_push_summary to be relatively small, so we can do this update
-- synchronously without impacting Synapse's startup time too much.
