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

see here:

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.
