openGauss storage SIG例会纪要会议时间：2022.4.16 14:30-16:30 与会人：熊小军彭炯吴岳川陈琛向新勇陈晓滨议题：发布订阅在gs_probackup备份恢复之后连接不断开特性设计评审特性需求来源：发布端在gs_probackup备份恢复后发布订阅无法正常运作，原因是gs_probackup并没有备份逻辑复制槽，而恢复后的发布端在接收订阅端逻辑复制的连接请求时，发现复制槽不存在而报错。具体方案（详见附件）：gs_probackup新增命令行参数--backup-pg-replslot，指定是否备份逻辑复制槽。对于wal日志备份起点的计算，在原先取最近一次checkpoint点为起点的基础上考虑所有复制槽中最小restart_lsn，以此进行wal日志的备份。目录pg_replslot则从排除列表pgdata_exclude_dir移除，使其能够备份。结论： 1. 方案采纳，补充要求gs_probackup工具只备份发布订阅的复制槽 2. 未来发布订阅的基础复制同步特性，需要考虑两个场景：订阅端原先没做过订阅，新建发布订阅关系；订阅端原先有订阅了，基础复制同步前需要清库，避免重复数据产生。
