I think that the patch should include some sort of notes in the documents to say that cluster performs freezing of tuples. I've attached a patch which adds something there, but I'm not 100% sure it is the right thing. Perhaps it should just read:
Cluster also performs aggressive "freezing" of tuples similar to VACUUM FULL FREEZE.
Although it's not exactly the same as you can perform a vacuum full freeze on a relation which does not have the clustered index set.
I'll delay a bit to see if anyone else has any comments about what the docs should read, but I think it is pretty much ready for a commiter's eyes.
Hi Thomas,
I'm just going to mark the patch as waiting for author for now until you get the chance to add some changes to the documents.
