Howdy,
First let me say thanks for the feedback! It is rare that we receive
detailed "user feedback" on these lists so it is good to hear from the
outside world. I am only going to address a few things as others have
addressed the rest.

I have to agree that pg_dump is largely a step child backup program. It has
consistently been found over the years to be lacking in a number of areas.
Unfortunately, working on pg_dump isn't sexy and it is difficult to get
volunteers or even paid resources to do such a thing. The real solution for
pg_dump is a complete refactor which includes pg_dumpall and it is not a
small undertaking. It should be noted that it is also a less and less used
program. On our team it is normally used for only very specific needs
(grabbing a schema) and we use binary backups or logical replication to
receive specific data.

This is really using the wrong tool for the job type of issue. PG was never
designed for such a scenario.

I think you are looking at this from a very windows centric way. Open
Source has its origins from the Unix paradigm where each tool was designed
to solve one type of problem and you used multiple tools to create a
"solution". Though we have strayed from that on some items due to the
evolving nature of software needs, that is still at our core and for good
reason. Having tools, flags etc... to do such things (including your point
#3) creates complexity best left to "vendors" not the software project.
