51.6. Examples

The PostgreSQL source distribution includes GIN classes for one-dimensional arrays of all internal types. The following contrib modules also contain GIN operator classes:

intarray: Enhanced support for int4[]
tsearch2: Support for inverted text indexing. This is much faster for very large, mostly-static sets of documents.
