please note that pg_dump --help shows:

hint: the part "for compressed formats" is critical.

plain dump is not compressed, you'd have to use -Fc to get compression,
but it's good to use anyway.

On previous versions the -Z 9 option would compress the plain text sql output to a gzipped file. Now it now longer compresses. Using the -Fc the outputs a compressed file, which is only readable
by pg_restore.
