我有一个像这样的功能 -

CREATE 
OR REPLACE FUNCTION ind (bucket text) RETURNS table (
    middle character varying (100),
    last character varying (100)
) AS $body$ BEGIN return query 
select 
  fname as first, 
  lname as last 
from all_records
; END;
$body$ LANGUAGE PLPGSQL;

如何将结果输出select ind ('Mob')到 tsv 文件中？

我希望输出看起来像这样 -

first   last
