Detaching multiple partitions in 1 ALTER TABLE statement

Hi,

I’m wondering what is the syntax for detaching multiple partitions in 1 ALTER TABLE statement.

I’ve tried this:

# ALTER TABLE movement_legs DETACH PARTITION movement_legs_2019_06_20_11_15, DETACH PARTITION movement_legs_2019_06_20_11_20;
psql: ERROR: syntax error at or near ","
LINE 1: ...gs DETACH PARTITION movement_legs_2019_06_20_11_15, DETACH P…

The documentation suggests "DETACH PARTITION can be combined into a list of multiple alterations to be applied together”:

https://www.postgresql.org/docs/12/sql-altertable.html

But I haven’t found an example of where multiple partitions are detached in 1 statement.

This is using version 12 beta 1.

Many thanks,

Ben
