68.1. Introduction

+ GiST stands for Generalized Search Tree. It is a + balanced, tree-structured access method, that acts as a base template in + which to implement arbitrary indexing schemes. B-trees, R-trees and many + other indexing schemes can be implemented in GiST. +

+ One advantage of GiST is that it allows the development + of custom data types with the appropriate access methods, by + an expert in the domain of the data type, rather than a database expert. +

+ Some of the information here is derived from the University of California + at Berkeley's GiST Indexing Project + web site and + Marcel Kornacker's thesis, + + Access Methods for Next-Generation Database Systems. + The GiST + implementation in PostgreSQL is primarily + maintained by Teodor Sigaev and Oleg Bartunov, and there is more + information on their + web site. +
