Tom Lane 5c8eb929e6 When telling the bgwriter that we need a checkpoint because too much xlog ... has been consumed, recheck against the latest value of RedoRecPtr before really sending the signal. This avoids useless checkpoint activity if XLogWrite is executed when we have a very stale local copy of RedoRecPtr. The potential for useless checkpoint is very much worse in 8.3 because of the walwriter process (which never does XLogInsert), so while this behavior was intentional, it needs to be changed.
