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
