By the way, can we teach pg_amcheck to verify database without creating local PGDATA and using bare minimum of file system quota?
We can implement a way for a pg_amcheck to ask for some specific file, which will be downloaded by backup tool and streamed to pg_amcheck.
E.g. pg_amcheck could have a restore_file_command = 'backup-tool bring-my-file %backup_id %file_name' and probably list_files_command='backup-tool list-files %backup_id'. And pg_amcheck could then fetch bare minimum of what is needed.
I see that this is somewhat orthogonal idea, but from my POV interesting one.
Best regards, Andrey Borodin.
