AW: pg_dump / pg_restore version confusion

I cannot use pg_restore v9.6 on a pg_dump v12 because otherwise: pg_restore: [archiver] unsupported version (1.14) in
fileheader 

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?
