Thread: question about database recover proceduers

Hello, 

     my pg version is 11, I use pg_basebackup+wal archive files to backup the database. I tried to restore the db to the latest wal archive file.

I restored the pg_basebackup file first,  restored wal archive files to the archive folder, and created the recovery.conf file, which only has the "restore_command" in it. 

when I started up the pg service, it didn't recover any wal archive files from archive folder with restore_command. 

may I know how pg determines which next wal archive file needs to be fetched from archive folder?

how to troubleshooting the recover procedure, and how to check if restore_command is called?

thanks, 

James

oh, I think I figured it out. I enabled the debug mode, 

log_min_messages = debug5

log_min_error_statement = debug5

and saw the recovery steps detail in the log file, it also shows the status of restore command.

it turns out my restore command had problem, after I fixed it, the db recovery works.

thanks

James
