The QUICK BROWN fox jumped over the LAZY dog
That's quite elegant. In the end I exported and used PERL, as some of my 'words' had spaces (they were ingredients like monosodium glutamate), but you could probably do a more complex regex in regexp_split_to_table to cope with that, or use pl/perl as previously suggested.
