Default Postgres privileges not showing on \ddp

As far as I understand there are set of default Postgres public privileges. I have created user and granted him privilege using:

CREATE USER foo WITH PASSWORD 'foo';
\connect bar;
GRANT SELECT ON ALL TABLES IN SCHEMA public to foo;

and I can connect to DB with no issues. Then I taught I must have connection privilege in the default privilege set, since I didn't grant connect on database explicitly. When I do \ddp I get 0 rows, and as far as I understood it is a way of checking default privileges per [this page](https://www.postgresql.org/docs/9.0/sql-alterdefaultprivileges.html) . Can someone help me understand how connecting to the DB is permitted when I haven't explicitly allowed it?
