Gin Index Hstore at Michael Doxey blog

Gin Index Hstore. A gin index stores a set of (key, posting list) pairs, where a posting. Hstore also supports btree or hash indexes for the =. The jsonb_path_ops class is intended to efficiently support containment queries. In this article, you learned what a gin index in postgresql is, how to define one, and its most important use cases. We can create these indexes as follows, Gin or gist (generalized search tree) indexes can improve network type queries: Create table product (id bigserial primary key, ext hstore); Create index hidx on testhstore using gist (h gist_hstore_ops(siglen=32)); This uses an optimized gin index structure that would instead store the above data as three individual entries using a hash function: Anyway, it doesn't matter if i create a gin or gist index, the explain keeps talking about sequential scan: Gin always stores and searches for keys, not item values per se. The hstore extension supports indexes of the gin type. I have the following constructor (as a test): Hashfn(field, value1), hashfn(field, value2) and hashfn(other_field, value42).
