Welcome to the Generalized Search Tree (GiST) access method for PostgreSQL. This document should help you get the code installed, and get you writing your own gist opclasses quickly.
GiST for PostgreSQL has been taken up by
the open source community. See this site for information.
Also, the PostGIS project is using the Postgres GiST implementation for their
Geographic Information System extensions to Postgres.
