This simplifies code that needs to do arithmetic on XLogRecPtrs. To avoid changing on-disk format of data pages, the LSN on data pages is still stored in the old format. That should keep pg_upgrade happy. However, we have XLogRecPtrs embedded in the control file, and in the structs that are sent over the replication protocol, so this changes breaks compatibility of pg_basebackup and server. I didn't do anything about this in this patch, per discussion on -hackers, the right thing to do would to be to change the replication protocol to be architecture-independent, so that you could use a newer version of pg_receivexlog, for example, against an older server version. |
