I've just noticed that you mentioned using 8.4 previously; there's a new
function called unnest in 8.4 that does the above. In your example it
would be:
SELECT unnest('{{A,B,C},{D,E,F}}'::text[]);
and you'd get back your six rows. It appears to do the correct thing
with arrays of higher dimensionality to me, but I only tried up to five.
