what do you do after pg_walreset ?
Hello, Please I wish to find out what you do after running pg_walreset. I made a mistake and deleted my data directory with all its content. I then restore with 1 day old backups, after that i could start unless i did pg_walreset. 1, I wish to find out what to do after i have started postgresql ? 2, How do I apply the wall files after the reset ? 3, How can I determine the amount of data lost ?
