I think it's worth a mention. See the text added in square brackets below:

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, [generate more
optimal plans for
queries containing aggregate functions with a `DISTINCT` or `ORDER BY` clause,]
utilize incremental sorts for `SELECT DISTINCT` queries, and optimize
window function
executions so they execute more efficiently. It also introduces
`RIGHT` and `OUTER`
"anti-joins", which enable users to identify rows not present in a joined table.

Thanks

David
