set the pgpass, still ask me password

All we need is an easy explanation of the problem, so here it is.

system: Ubuntu 20.
related post: PostgreSQL: Using the .pgpass file
https://unix.stackexchange.com/questions/117467/how-to-permanently-set-environmental-variables/117470#117470
overall means I permanent set the following enviroment variable in /etc/profile

export PGPASSFILE='/home/jian/.pgpass'
export PSQLRC='/home/jian/.psqlrc'
export PGUSER=admin
export PGDATABASE=test
export PGPORT=5433

I also did sudo chmod 600 /home/jian/.pgpass

 sudo cat /home/jian/.pgpass

return

localhost:5433:test:admin:password
localhost:5432:test:admin:password

when I type psql, it still promopt me to password. I thought all things are properly set.
later I deleted the second password line, still ask me password.
