The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/9.6/app-pgbasebackup.html Description:
Only since Postgres 10, one can take backup of wals along with full backup (in tar format) using pg_basebackup ERROR: pg_basebackup: WAL streaming can only be used in plain mode Try "pg_basebackup --help" for more information You dont see that error since Postgres 10 instead you see a separate tar file for wals.
