Hi , I am experimenting with PITR aspect of postgres8.0, and I needed some answers on this subject. I have following questions : 1) At time t0, I created a base backup. (got a backup marker file named as: 0000000800000002000000A8.005E61B4.backup) (assume no previous base backups and recoveries...) On time t2 I did a recovery till time t1 ( t0<t1<t2). Now I see history file named 00000009.history. And then onwards, the WAL filenames start with 00000009. Is 00000009 here the new timeline ? If so is it safe to deduce that from .history file that gets generated after recovery ? 2) Now say, I was happy with the above recovery and after a few days, at time t3 I decided to revover my db back in time t. What timeline should I specify in recovery.conf if: (or do I need to specify it in each case?) a) t1 < t < t2 b) t2 < t < t3 IMO, in case a) the timeline of base backup would be used, so I wouldn't need to specify timeline. While in case b) I need to specify this new timeline(recovery_target_timeline=00000009). Kindly confirm... trying to put the scenario pictorially: t0 t2 | t1 | |-------| ------ |---------- timeline: 00000008 | | timeline:00000009 |----------------------|---- t3 TIA, Satya __________________________________________________ Do You Yahoo!?
