can't create table on new db/schema/user

What I have:

    debian 10 
    postgresql 11.7-0+deb10u1

What I did:

    sudo -s
    mkdir           /var/lib/postgresql/11/ts_chris
    chown postgres: /var/lib/postgresql/11/ts_chris
    chmod 700       /var/lib/postgresql/11/ts_chris

    su - postgres -c psql
    create user "chris" with login password '***' connection limit -1;
    create tablespace "ts_chris" owner    chris location '/var/lib/postgresql/11/ts_chris';
    alter  tablespace ts_chris   owner to chris;
    create database   db_chris   owner =  automicuser template = template0 encoding = "UTF-8" tablespace = ts_chris
lc_collate= "C" lc_ctype = "C" connection limit = -1 ;
 
    create schema     s_chris    authorization "chris";
    alter  role       chris      in database db_chris set search_path to s_chris;
    grant usage  on schema   s_chris  to chris;
    grant create on schema   s_chris  to chris;

What I tried:

    psql -h lxc05 db_chris chris

    db_chris=> create table t1 (i int);
    ERROR:  no schema has been selected to create in
    LINE 1: create table t1 (i int);
                         ^

So, what did I miss?
