printing a value of a variable in postgresql

I have a postgresql function

CREATE OR REPLACE FUNCTION fixMissingFiles() RETURNS VOID AS $$
DECLARE
    deletedContactId integer;
    BEGIN
            SELECT INTO deletedContactId contact_id FROM myContacts WHERE id=206351;

            -- print the value of deletedContactId variable to the console

    END;
$$ LANGUAGE plpgsql;

How can I print the value of the deletedContactId to the console?

Answer

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;
