Thank you for elaborating!! pgadmin 4 is a great product.
I still hope that in some future at least the explorer view can get the "Aggregates" node, at least as an informational one. From my experience most of the time creating DB objects (tables, functions, etc) is done via a script so the UI to create DB objects is rarely used. However when it comes to exploring DB structure a lazy sloth like DB developer likes the explorer tree :) It is far more convenient to navigate the tree than to type queries.
