Re: clarification for pg_basebackup and major versions - Mailing list pgsql-docs
Hi, Team !
Some more clarification about pg_basebackup which should be available in the documentation:
- if pg_basebackup works between different versions of the same OS (ex. RHEL8 and RHEL9)
- if pg_basebackup works between different types of OS Linux (ex. RHEL10 and Debian13) or OS Windows (ex. Windows 2016 and Windows 2019)
- if pg_basebackup works between different types of OS (ex. Ubuntu 24.04 and Windows 2022)
- if pg_basebackup works between different platforms (ex. Linux on amd64 and Linux on arm64)
- if pg_basebackup works between 32-bit OS and 64-bit OS
best regards,

- to clarify how pg_basebackup works with servers of the same or older major
versionThere is no “how”, it just does. The documentation is versioned and “it” means the binary produced by that version.- to clearly specify pg_basebackup cannot be used for PostgreSQL major
version upgradeThe page clearly states what a backup can be used for and upgrade is not listed.David J.
