This section provides an overview of TOAST (The Oversized-Attribute Storage Technique).

SP-GiST offers an interface with a high level of abstraction, requiring the access method developer to implement only methods specific to

GiST stands for Generalized Search Tree. It is a balanced, tree-structured access method, that acts as a base template in which to implement

The core PostgreSQL distribution includes the BRIN operator classes shown in Table 64-1.

GIN assumes that indexable operators are strict. This means that extractValue will not be called at all on

Each heap and index relation, except for hash indexes, has a Free Space Map (FSM) to keep track of available space in the relation. It's stored alongside the main relation

The genetic algorithm (GA) is a heuristic optimization method which operates through randomized search. The set of possible solutions for

Internally, a GIN index contains a B-tree index constructed over keys, where each key is an element of one or more indexed items (a member

The PostgreSQL source distribution includes GIN operator classes for tsvector
