I had missed the fact that this commit added a bunch of read and write barriers; and I think that's the main reason why I was concerned. The existence of those barriers, and the invariants they are intended to maintain, makes me feel better about it. Thanks for writing back about this! -- Robert Haas EDB: http://www.enterprisedb.com
