Is pg_restore in 10.6 working?

I have some experience with different versions of Postgres, but I'm just
getting around to using pg_restore, and it's not working for me at all.

I can connect with psql, and pg_dump works, but pg_restore never does
anything when I call it. It never even prompts for a password.

Here is my pg_hba.conf:
# "local" is for Unix domain socket connections only
local all all ident
map=super
# IPv4 local connections:
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 ident
# Allow replication connections from localhost, by a user with the
# replication privilege.
local replication all peer
host replication all 127.0.0.1/32 ident
host replication all ::1/128 ident

And my pg_ident.conf
# MAPNAME SYSTEM-USERNAME PG-USERNAME
super ec2-user postgres

I can connect with psql either of these two ways:
psql -U postgres
or
psql -h ip-172-31-62-127.ec2.internal -p 5432 -U postgres -W postgres
(Yes, it's an AWS server)

This pg_dump command works:
pg_dump -U postgres -f predata.sql -F p -v -d prod_data

But a matching pg_restore command does nothing.
pg_restore -U postgres -f predata.sql -v

I'm running 10.6.

thank you
