All,
I have a suggestion for the rmgr patch.
Currently, there are *no* plans to get WAL working for the new hash
indexes, nor is there time.
I suggest that we take the rmgr patch and combine it with getting WAL
working properly for Bitmap-on-disk and Hash indexes in 8.5. Having
this patch attached to an actual implementation will show if it's the
correct code to make building new types of indexes easier, or not,
rather than arguing about it in the abstract.
In other words, I'm suggesting that we move it to commitfest-first for
8.5. It's not like we don't have plenty of features and uncommitted
patches for 8.4, and it's not like Simon is going away.
