Hackers,

I see that design question for PostgreSQL pluggable storages is very hard.  BTW, I think it worth analyzing existing use-cases of pluggable storages.  I think that the most famous DBMS with pluggable storage API is MySQL.  This why I decided to start with it.  I've added MySQL/MariaDB section on wiki page.
https://wiki.postgresql.org/wiki/Future_of_storage#MySQL.2FMariaDB
It appears that significant part of MySQL storage engines are misuses.  MySQL lacks of various features like FDWs or writable views and so on.  This is why developers created a lot of pluggable storages for that purposes.  We definitely don't want something like this in PostgreSQL now.  I created special resume column where I expressed whether it would be nice to have something like this table engine in PostgreSQL.

Any comments and additions are welcome.  I'm planning to write similar table for MongoDB.
