usando PL/Perl tente assim:

CREATE FUNCTION funcname (argument-types) RETURNS return-type AS $$
    system("cp /home/fonte/teste.txt /home/destino/");
$$ LANGUAGE plperl;

isso deve copiar o arquivo teste.txt localizado em /home/fonte para /home/destino

Veja se tem algo errado

CREATE OR REPLACE FUNCTION copy_file() RETURNS integer AS $$
    system("cp /home/teste.txt /");
RETURN 0;
$$ LANGUAGE plperl;

Está retornando o seguinte erro!

ERROR: creation of Perl function failed: 'system' trapped by operation mask at (eval 4) line 2.
