Hi, Team ! Thanks for your reply !
What I see in the fields is the lack of such simple supported/recommended/prerequisites notes/links in the official PostgreSQL documentation (pg_backup is just an example). That might lead to further confusion for PostgreSQL users. As an example pls. let me share the logical replication documentation https://www.postgresql.org/docs/current/logical-replication.html which says: ' ... - Replicating between different major versions of PostgreSQL. - Replicating between PostgreSQL instances on different platforms (for example Linux to Windows) ... ' I do believe something similar about pg_basebackup would be very welcome by PostgreSQL users. best regards, Alexey Shishkin [image: image.png] *Alexey Shishkin* Technical Account Manager EDB Software GmbH [email protected] www.enterprisedb.com <https://enterprisedb.com/> On Mon, Jan 19, 2026 at 7:23 PM David G.
