[root@dbch ~]# sudo -u enterprisedb pgbackrest --stanza=Repo1 --delta --set=20240922-232733F_20240925-082637I --target-timeline=current restore
2024-09-25 10:28:42.493 P00 INFO: restore command end: completed successfully (2657236ms)
Now I comment out the archive command in the test EPAS server postgresql.conf and started the EPAS server.
WHen I issue a query to select few rows To my surprise I am seeing the records with columns with time stamp up to a time 10.36:11:968 and 10:36:13.363 :
How did this happen ? I specified the restore point file (incr) taken at 2024-09-25 08:26:37, naturally I expected restore may show records up to this time stamp or up to 2024-09-25 08:36:00+05:30 but it shows further to 10.36:11:968 and 0:36:13.363 but not beyond this !!!
But my restore ends successfully at 2024-09-25 10:28:42.493 P00 INFO: restore command end: completed successfully (2657236ms)
Could someone explain how this comes about ?
But no other records latest than 10.36:11:968 and 0:36:13.363 showing .. How is it delimited here at this time stamp ?
SO I guess this is due to specifying --target-timeline=current ? But restore finished at 10.28:42.493
OR
Does this take all wal and replay up to the EPAS service starting time of the testing EPAS server ?
Thank you,
Krishane.
