In summary, we don't do any version check for built-in function pushdown, so we don't need it for aggregates either. We check extension functions against the extension pushdown list, so we should be checking this for partial aggregate pushdown, and for partition-wise aggregate pushdown. If we don't do that last check already, it is a bug. -- Bruce Momjian <br...@momjian.us> https://momjian.us EDB https://enterprisedb.com Embrace your flaws.
