Hi, While reviewing another patch, I noticed that it slightly adjusted the treatment of datlastsysoid. That made me wonder what datlastsysoid is used for, so I started poking around and discovered that the answer, at least insofar as I can determine, is "nothing". The documentation claims that the value is useful "particularly to pg_dump," which turns out not to be true any more. Tom's recent commit, 30e7c175b81d53c0f60f6ad12d1913a6d7d77008, to remove pg_dump/pg_dumpall support for dumping from pre-9.2 servers, removed all remaining uses of this value from the source tree. It's still maintained. We just don't do anything with it.
Since that doesn't seem like an especially good idea, PFA a patch to remove it. Note that, even prior to that commit, it wasn't being used for anything when dumping modern servers, so it would still have been OK to remove it from the current system catalog structure. Now, though, we can remove all references to it. -- Robert Haas EDB: http://www.enterprisedb.com
