Re: PostgreSQL 16 release announcement draft

>>>
PostgreSQL 16 improves the performance of existing PostgreSQL functionality
through new query planner optimizations. In this latest release, the query
planner can parallelize `FULL` and `RIGHT` joins, utilize incremental sorts for
`SELECT DISTINCT` queries, and execute window functions more efficiently. It
also introduces `RIGHT` and `OUTER` "anti-joins", which enable users to identify
rows not present in a joined table.
>>>

I think "utilize incremental sorts is for" something like select
my_avg(distinct one),my_sum(one) from (values(1),(3)) t(one);
so it's not the same as `SELECT DISTINCT` queries?

<<<< "the query planner ....., and execute window functions more efficiently."
since the query planner doesn't execute anything. probably "and
optimize window functions execution"?
