Hello Dmitry and Alexander,

Please look at one more anomaly with temporary tables:
CREATE TEMP TABLE t (a int) PARTITION BY RANGE (a);
CREATE TEMP TABLE tp_0 PARTITION OF t FOR VALUES FROM (0) TO (1) ;
CREATE TEMP TABLE tp_1 PARTITION OF t FOR VALUES FROM (1) TO (2);
ALTER TABLE t MERGE PARTITIONS (tp_0, tp_1) INTO tp_0;
-- succeeds, but:
ALTER TABLE t SPLIT PARTITION tp_0 INTO
   (PARTITION tp_0 FOR VALUES FROM (0) TO (1),  PARTITION tp_1 FOR VALUES FROM (1) TO (2));
-- fails with:
ERROR:  relation "tp_0" already exists

Though the same SPLIT succeeds with non-temporary tables...

Best regards,
Alexander
