is there still a memory leak with hash joins in PG 12.11 ?

Hi,

We are running on PG 12.11.

We recognized an evergrowing memory usage.

work_mem = 50M

there are some regularly hash joins.

I found this blog post talking about a memory leak having hash joins due to a larger work_mem.

Does anyone know if this problem is still there in PG 12.11 ?

Thanks,

Markus
