PG11 基于时间点恢复在时间线上无限循环

This topic created in 1672 days ago, the information mentioned may be changed or developed.

restore_command = '/usr/bin/lz4 -f -q -d /data/database/1/backup/%f.lz4 %p'
recovery_target_action = 'promote'
recovery_target_inclusive = false
recovery_target_time = '2021-10-24 17:19:00'

正常恢复完 wal 后

日志里不停循环

这啥问题啊,一晚上了没解决,要哭了呀

源数据没有启过新时间线,不知道为什么恢复的时候会无限寻找“下一个时间线”
升级到 11.13 也没用...感觉不找到最大时间线不停了....
