Right. And I'm saying that pluggability is PostgreSQL's main reason for
existence, if you look at our place in the future of databases. So it's
worth paying *some* cost, provided that the cost/benefit ratio works for
the particular patch.
To rephrase: I can't judge the rmgr patch one way or the other. I'm
only objecting to the idea expressed by Heikki and others that pluggable
indexes are stupid and unnecessary.
