Re: Commitfest 2023-03 starting tomorrow! - Mailing list pgsql-hackers

Hi,
 
After catching up with this thread, where pending bugs are listed and discussed,
I wonder if the current patches trying to lower the HashJoin memory explosion[1]
could be added to the "Older bugs affecting stable branches" list of
https://wiki.postgresql.org/wiki/PostgreSQL_16_Open_Items as I think they
deserve some discussion/triage for v16?

The patch as it stands is not invasive. As I wrote previously[2], if we
couldn't handle such situation better in v16, and if this patch is not
backpatch-able in a minor release, then we will keep living another year, maybe
more, with this bad memory behavior. 

Thank you,
