Hello Andrian,
Thank you
> Have you even tried a schema only dump from the original instance?
That's an odd question. However, I understand that maybe a lot of beginners
come onto this mailing list.
To the contrary, this is a non-trivial situation.
You can safely assume that I wrote the original request because all the
other approaches failed to bring a result. Everything has already been tried
and tested.
The only question remains the one in the subject line.

This is an incorrect assumption.
Most of the information is available.
Just the PostgreSQL server can't work with it [because of the missing bits].
Kind regards,
Tomas
