I cannot use pg_restore v9.6 on a pg_dump v12 because otherwise: pg_restore: [archiver] unsupported version (1.14) in file header
The external supplier did PG v9.5 database + pg_dump v12.
I would have to do pg_restore v12 (as of pg_dump v12) into my PG v9.6.
The version chain would be PG v9.5 => pg_dump v12 => pg_restore v12 => PG v9.6.
That's why my question has been: would the whole chain work and is it supported?
That is one way of attempting it, though it is not supported. You could
also try pg_restore v12 on pg_dump file v9.6 to Postgres v9.6 database
as well. With the caveats that I quoted in my previous post. Ideally you
would have the supplier redo the dump of the database with a 9.6 version
of pg_dump.

Would a pg_restore with a v12 client into a postgres v9.6 database work and be
officially supported?

Uh, good question. You should still use the version of pg_restore that you are
loading _into_, not what you dumped from.
