Re: stable vs. immutable unaccent function

Hi,

I wrote the unaccent_text wrapper function to achieve the following:

CREATE INDEX table_name_label_unaccent_idx
  ON table_name
  USING gin
  (unaccent_text(label::text) COLLATE pg_catalog."default" gin_trgm_ops);

I would have liked to use unaccent directly.

The fact that someone wrote such a comment should be a clue that it's a

My comment. I acknowledge it was a hack. Couldn't see how to add the
unaccented index (without adding an extra column, which is just another
hack). ;-)

A proper solution, Marti, I thank you for: using the STABLE unaccent
function from MusicBrainz. I'll take a look -- hopefully it works with 9.1.
