Hi folks,

  I'm in the process of implementing PITR backups and restores and learning
as I practice. I restored

 Using tar -xzf  (backup-name) followed by restarting postgres and having
the server replay the logs.

  I used a recovery_target_time of 1 day prior to current_date  Postgres
seems to come up OK but

  I get the following message over and over again in the serverlog:


      ERROR:  xlog flush request F/83462374 is not satisfied --- flushed
only to F/82FFF0AC

     CONTEXT:  writing block 1242336 of relation 1663/16388/17696


  The logs that came into play in the replay are (in shorthand)

       80, 81, 82.   The log that was copied back into xlog was 83 prior to
the restore.

 The relation in the error message points back to a table that was indeed
being updated

 While the backup was being done.


When I attempt to do another backup I get an error that the checkpoint
request failed.


Is there any way replay the restore to get out of this pickle, or do I start
from scratch?


Fortunately this is a development server so I have the luxury of recopying
