Looks good to me. Would ideally like to see some tests: should be easy enough to add to t/002_pg_dump.pl, but probably not worth it just for a simple flag like this? We don't test a lot of other flags, but on the other hand, that's what a test suite is supposed to do.
hi.
around src/bin/pg_dump/pg_dump.c line 1117
right after "ropt->no_comments = dopt.no_comments;"
we also need add
ropt->no_policies = dopt.no_policies;
?
overall looks good to me.
The tests seem wrong per

I have no idea how to improve the test.
