What this describes is how to modify Postgres to request huge pages. That's hardly built-in support. In any case, as David already explained, we don't do feature additions in minor releases. We'd be especially unlikely to make an exception for this, since it has uncertain portability and benefits. Anything that carries portability risks has got to go through a beta testing cycle before we'll unleash it on the masses. regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
