Recovery of a corrupted wallet

I have a very old wallet.dat that I've put into my .bitcoin folder. When trying to run bitcoind, the service stops giving the following error

2019-06-11T18:14:02Z Using wallet directory /home/nom/.bitcoin

Edit. Here is the content of the DB log

file unknown has LSN 1/151495, past end of log at 1/28 Commonly caused by moving a database from one database environment to another without clearing the database LSNs, or by removing all of the log files from a database environment Page 0: metadata page corrupted Page 0: could not check metadata page wallet.dat: DB_VERIFY_BAD: Database verification failed file unknown has LSN 1/151495, past end of log at 1/1080 Commonly caused by moving a database from one database environment to another without clearing the database LSNs, or by removing all of the log files from a database environment wallet.dat.1560341204.bak: DB_VERIFY_BAD: Database verification failed file unknown has LSN 1/151495, past end of log at 1/2500 Commonly caused by moving a database from one database environment to another without clearing the database LSNs, or by removing all of the log files from a database environment wallet.dat.1560341352.bak: DB_VERIFY_BAD: Database verification failed

Edit. Using db_dump I am able to see the content of the wallet file ( addresses, keys etc)

Is there any way I could debug this, perhaps recovering just part of the keys or any useful data from the DB itself? Any useful hints how to approach such recovery?
