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.
