Run default demo cluster. When I create AO temporary table and drop it, the table files are not deleted.

CREATE TABLESPACE
postgres=# CREATE TEMP TABLE ts(i INT)
   WITH (APPENDOPTIMIZED = TRUE)
   TABLESPACE tts_tblspace
   DISTRIBUTED BY (i);
CREATE TABLE
postgres=# select relfilenode from pg_class where oid=(select relid from pg_appendonly);
