50.4. Examples

The PostgreSQL source distribution includes several examples of index methods implemented using GiST. The core system currently provides R-Tree equivalent functionality for some of the built-in geometric data types (see src/backend/access/gist/gistproc.c). The following contrib modules also contain GiST operator classes:


B-Tree equivalent functionality for several data types


Indexing for multidimensional cubes


RD-Tree for one-dimensional array of int4 values


Indexing for tree-like structures


Text similarity using trigram matching


Indexing for "float ranges"


Full text indexing
