Dear All,
Good morning, I have a small doubt regarding a partitioned table, which has its "mother" table and many "daughter" tables, well the main question is... I need to reduce the size of my partitioned table, I can simply delete ( drop table) the oldest daughter tables??? or it is not recommended....or maybe there is another method to do this??
From already thank you very much

Dropping an individual partition using DROP TABLE, or doing ALTER TABLE DETACH PARTITION, is far faster than a bulk operation. These commands also entirely avoid the VACUUM overhead caused by a bulk DELETE.
