GiST home | Introduction | ... GiST is a height-balanced tree structure with tree nodes containing (p, ptr) pairs, where p is a predicate ( attribute ),which is used as a search key, and ptr is the pointer to data for a leaf node or a pointer to another tree node for a non-leaf node. ... Every node contains between min and max index entries unless it is the root . ... For each index entry (p, ptr) in a non-leaf node, p is true when instantiated with the values of any tuple reachable from ptr . ...
