i made a small patch which i found useful for my personal tasks.
it would be nice to see this in 8.5. if not core then maybe contrib.
it transforms a tsvector to table format which is really nice for text 
processing and comparison.

test=# SELECT * FROM tsvcontent(to_tsvector('english', 'i am pretty sure 
this is a good patch'));
  lex   | rank
 good   |    8
 patch  |    9
 pretti |    3
 sure   |    4

    many thanks,
