PostgreSQL
62.5. Examples
The PostgreSQL source distribution includes several examples of index methods implemented using GiST. The core system currently provides text search support (indexing for tsvector and tsquery) as well as 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:
btree_gist-
B-tree equivalent functionality for several data types
cube-
Indexing for multidimensional cubes
hstore-
Module for storing (key, value) pairs
intarray-
RD-Tree for one-dimensional array of int4 values
ltree-
Indexing for tree-like structures
pg_trgm-
Text similarity using trigram matching
seg-
Indexing for “[.quote]#float ranges”#
