Hmm, yeah. So -U works but not the env variable. I would file a bug 
report(https://www.postgresql.org/account/login/?next=/account/submitbug/):

aklaver@tito:~> env | grep PGUSER
PGUSER=postgres

/usr/local/pgsql12/bin/initdb   -D pg_test_postgres/
/usr/local/pgsql12/bin/pg_ctl -D pg_test_postgres start

aklaver@tito:~> psql -d postgres -U postgres -p 5429
