    You can’t specify a non-default user with -U in psql when using ident authentication. You won’t be running psql as that user, so auth will fail.

    You must either use sudo -u testuser psql test or change pg_hba.conf so that authentication (at least for testuser on the db test) uses md5 password authentication, and set a password for testuser with ALTER USER ... PASSWORD if they don’t have one already.
