Bruce,
Plugability adds complexity. Heikki's comment is that adding this patch make the job of creating pluggable indexes 5% easier, while no one is actually working on plugable indexes, and it hard to say that making it 5% easier really advances anything, especially since many of our existing index types aren't WAL-logged. Plugability is not a zero-cost feature.
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.
