Runtime partition pruning

Hello list,

Is runtime partition pruning available in PostgreSQL 12?

I have a table partitioned by range on column id (primary key).
For the query (client_id is passed as a parameter from the application):

select * from test where id between>0 and and id<1000 and client_id=? ;

partition pruning works fine.

However

select * from test where id between client_id-10 and client_id+10 and
client_id=?;

does not (it scans all partitions in parallel) .
Is it expected?

Regards,
Radu
