Are you talking about this view?:
https://www.postgresql.org/docs/10/static/view-pg-shadow.html
If so that is only readable by superusers:
production=# \c - aklaver
You are now connected to database "production" as user "aklaver".
production=> select * from pg_shadow ;
ERROR: permission denied for relation pg_shadow
production=> \c - postgres
You are now connected to database "production" as user "postgres".
production=# select * from pg_shadow ;
usename | usesysid | usecreatedb | usesuper | userepl |
usebypassrls | passwd | valuntil | useconfig
...
Assuming someone is in your database as a superuser, access to the
password field in pg_shadow is pretty much moot.
