Get DB owner's name in PostgreSql

Question

I have DB \"test\" in PostgreSql. I want to write sql to get owner my database.

Answer 1

This work with database owned by group role:

SELECT
    U.rolname
   ,D.datname
FROM
    pg_roles AS U JOIN pg_database AS D ON (D.datdba = U.oid)
WHERE
    D.datname = current_database();

Using pg_authid (as I did in my previous version) instead of pg_roles is limited to SuperUser because it holds password (see documentation):

Since this catalog contains passwords, it must not be publicly readable. pg_roles is a publicly readable view on pg_authid that blanks out the password field.
