Hi, running 11.5 I've got a partitioned table where I want to destroy an index (on a column that has nothing to do with the partition): respidb=# \d+ respi.root Column | Type | --------------+-----------------------------+- sen_id | integer | mis_flusso | integer | mis_tasso | integer | mis_velocita | integer | mis_ora | timestamp without time zone | pk | bigint | ts | timestamp without time zone | Partition key: LIST (date_part('year'::text, mis_ora)) Indexes: "idx_root_sensore" btree (sen_id) "idx_ts" btree (ts) Partitions: respi.y2018 FOR VALUES IN ('2018'), PARTITIONED, respi.y2019 FOR VALUES IN ('2019'), PARTITIONED, respi.y2020 FOR VALUES IN ('2020'), PARTITIONED respidb=# drop index idx_root_sensore; ERROR: index "idx_root_sensore" does not exist Of course the index exists: SELECT oid, relname, relkind FROM pg_class WHERE relname = 'idx_root_sensore'; -[ RECORD 1 ]------------- oid | 40950 relname | idx_root_sensore relkind | I I already did a manual vacuum on the table. Any idea? Luca
