Hi Oliver,
You can use tableoid system column of table for filtering.
select tableoid::regclass,* from parent_table where tableoid::regclass in ('p2','p4');
Best regards.
İyi çalışmalar.

Hi,
I wonder how could it be possible to extract partitions that contains a peculiar item
Consider 4 partitions 1, 2, 3, 4 with different items A, B, C... inside
P item
1 A
1 B
1 C
2 B
2 D
2 G
2 H
3 B
3 C
4 X
4 D
4 Z
How could a select return partitions 2,4 because they both contains D item ?
As a result, I would get :
2 B
2 D
2 G
2 H
4 X
4 D
4 Z
I can filter partitions with lag, lead, nth_value... but how could I write something like "select P,any (item=D) over (partition by P) from..."
Thanks for any help,
