It looks like this was broken just before 10.10 was released, and has since been fixed;
see:
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=6844adba54f7d96f30f834efc6d9aa1e52e5672d
Your options are:
- find a 10.9 or earlier package and use the pg_dump from that
- build pg_dump yourself
- wait for 10.11 to come out (though I imagine that won't be for a month or two)
