I write more detail(*). Record-A and Record-B are cross segment-border records. Record-A spans segment X and X+1. Record-B spans segment X+2 and X+3. If both records have been inserted to WAL buffer, lastSegContRecStart/End points to Record-B * If a writer flushes segment X and a part of X+1 but record-A is not flushed completely, NotifyStableSegments() allows the writer to notify segment-X. Then, Record-A may be invalidated by crash-recovery and overwritten by new WAL record. The segment-X is not same as the archived one. Regard Ryo Matsumura
