I believe that’s a problem with incompatible Postgres versions.

A stupid question most likely, but are both Discourse instances on the same version?

I recently saw a restoration failure, when I had the target system accidently built on tests-passed and the source was a significantly older stable.

I’ve solved this probem by run psql manually.
just psql db < xxx.sql is works.
