This only seems to show up in pgadminIII, I am unable to see this grant using \dn+(but I am a bit of a novice).
postgres=# \dn+
List of schemas
Name | Owner | Access privileges | Description
--------+----------+----------------------+------------------------
public | postgres | postgres=UC/postgres+| standard public schema
| | =UC/postgres |
I would seem to me granting "public" access to the schema by default is bad. Granting access to just the required users is good.
Good:
CREATE SCHEMA public
AUTHORIZATION postgres;
GRANT ALL ON SCHEMA public TO postgres;
COMMENT ON SCHEMA public
Bad and happens to be the default:
CREATE SCHEMA public
AUTHORIZATION postgres;
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
COMMENT ON SCHEMA public

Thanks for clearing that up.
I seems that any database that gets created has "GRANT ALL ON SCHEMA public TO public" by default. These are all clean installs. I have found this on Ubuntu 9.3, The Postgres 9.3 and 9.4 deb packages.
Default postgres from ubuntu, is the version I am testing on.
It seems to be the default install, though we might be a patch or two behind.
$ dpkg -l | grep postgres
ii postgresql-9.3 9.3.5-0ubuntu0.14.04.1 amd64 object-relational SQL database, version 9.3 server
I found this problem on a install from the postgres repo
$ dpkg -l postgresql-9.3
