The following script: CREATE TABLE t (a integer) PARTITION BY RANGE (a); CREATE TABLE tp (a integer PRIMARY KEY); ALTER TABLE t ATTACH PARTITION tp FOR VALUES FROM (0) TO (1000);
CREATE UNIQUE INDEX t_a_idx ON t (a); ALTER INDEX t_a_idx ATTACH PARTITION tp_pkey;
\d+ t* ALTER TABLE t DETACH PARTITION tp;
