maia_languages table encoding

[mortonda@…]

Need to fix the maia_languages table to have utf-8 encodings. Might want to use ​http://www.loc.gov/standards/iso639-2/ascii_8bits.html to refresh and update.

Also of interest: A ​procedure to update or insert on postgresql:

CREATE TABLE db (a INT PRIMARY KEY, b TEXT);

CREATE FUNCTION merge_db(key INT, data TEXT) RETURNS VOID AS
$$
BEGIN
    LOOP
        -- first try to update the key
        UPDATE db SET b = data WHERE a = key;
        IF found THEN
            RETURN;
        END IF;
        -- not there, so try to insert the key
        -- if someone else inserts the same key concurrently,
        -- we could get a unique-key failure
        BEGIN
            INSERT INTO db(a,b) VALUES (key, data);
            RETURN;
        EXCEPTION WHEN unique_violation THEN
            -- do nothing, and loop to try the UPDATE again
        END;
    END LOOP;
END;
$$
LANGUAGE plpgsql;

SELECT merge_db(1, 'david');
SELECT merge_db(1, 'dennis');

and for ​mysql

On second thought, while it may not be entirely correct, it only matters when we have a translation ready. Let's not waste time on this now.
