Improper formatting for `TRIGGER`s when `OR REPLACE` is used

[hexcowboy]

When formatting a trigger, using OR REPLACE will cause bad indentation.

Here's a fully reproducible file with the two behaviors marked with comments:

create table if not exists my_table (
  id serial primary key,
  updated_at timestamp not null default now()
);

create or replace function trigger_set_timestamp ()
  returns trigger
  language plpgsql
  as $$
begin
  new.updated_at := current_timestamp;
  return new;
end;
$$;

-- Improper indentation with `OR REPLACE`
create or replace trigger set_timestamp before update on my_table for each row execute function trigger_set_timestamp ();

-- Proper indentation without `OR REPLACE`
create trigger set_timestamp
  before update on my_table for each row
  execute function trigger_set_timestamp ();
