See the GRANT statement:
https://www.postgresql.org/docs/current/sql-grant.html

If it is not on your "search_path", use schema_name.table_name to reference
the (foreign) table.

It is all in the PostgreSQL documentation.

That is nologin role and no real role at all.
It is a way to say "everybody".


I recommend that you spend a few hours with the PostgreSQL documentation,
reading up on schemas (https://www.postgresql.org/docs/current/ddl-schemas.=
html),
privileges (https://www.postgresql.org/docs/current/ddl-priv.html) and
roles (https://www.postgresql.org/docs/current/user-manag.html).

Perhaps then it will start making more sense.

Yours,
