Hi Jack, I'd recommend first to start from official documentation on index access methods [0]. Please also check the contrib/bloom module [1]. It is designed to showcase index-as-extension technology. Also, you can see my free lectures about details of implementation of built-in access methods [2]. Also, I can offer you my PGCon talk "Index DIY" about forking GiST into extension [3]. Thank you! Best regards, Andrey Borodin.
