Query-Sending mail from PostgresSQL

Hi,

We are using Postgres. Doing migration from Oracle to Postgres SQL. Now we
wanted to migrate the Sending mail operation as in oracle. Searched the
help couldn't able to find the solution.  Below is the oracle statement
used.

UTL_MAIL.send(
                sender     =>  EMAIL_DIST,
                recipients =>  EMAIL_DIST,
                cc         =>  EMAIL_DIST,
                bcc        =>  EMAIL_DIST,
                subject    =>  Load_Name ,
                message    =>  emesg
                );

Please give your suggestion how we can migrate the above statement to
Postgres.

Thanks
