> We have implemented multi-key index support for GiST. Patch is available
> from http://www.sai.msu.su/~megera/postgres/gist/code/7.1.2/patch_multikeygist.7.1.2.gz
> The patch could be applied for postgresql version 7.1.2 and current sources 7.2
>
> 1. initdb is required. But, it's possible just to execute update
> update pg_am set amstrategies = 12 where amname = 'gist';
>
> 2. You have to recompile all gist_*_ops functions
>
> 3. multi-key indexes works only for ??? gist__int_ops and
> gist__intbig_ops (from contrib/intarray), because they have
> support for NULLs.
>
> As a bonus we fixed several memory leaks in old GiST code.
>
>
> Example:
>
> create index mgix on tabletest using gist (b gist_int_ops, a
> gist__intbig_ops ) with ( islossy );
