- <para>
- The current implementation of <acronym>GiST</acronym> within
- <productname>PostgreSQL</productname> has some major limitations:
- <acronym>GiST</acronym> index access is not concurrent, and the
- <acronym>GiST</acronym> interface doesn't allow the development of
certain
- data types, such as digital trees (see papers by Aoki et al).
- </para>
AFAIK the GiST modifications suggested Aoki have not yet been
implemented, so this should not have been removed.
I thought that was an extremely vague limitation and could easily be
removed... It's like having a limitations section on btrees and have
mentioning in passing that it can't do full text indexing or something.
