Hi,
in the Postgres documentation it says: "PostgreSQL provides the index methods B-tree, hash, GiST, SP-GiST, GIN, and BRIN. Users can also define their own index methods, but that is fairly complicated." (https://www.postgresql.org/docs/12/sql-createindex.html)
Even though it's described as fairly complicated: If I would want to define my own index method, what would be a good approach to do so?
Best regards
