The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/18/app-pgbasebackup.html Description:
Hi, Team ! Could we pls. clarify the following statement on the documentation page https://www.postgresql.org/docs/18/app-pgbasebackup.html: 'pg_basebackup works with servers of the same or older major version, down to 9.1.' What does it exactly mean 'works with servers of the same or older major version' ? Most probably it means the possibility to use pg_basebackup binary of version PG 17 to take backup of PG 14 server. Or something else ? But it's definitely not ability to use pg_basebackup for PostgreSQL major version upgrade, since pg_basebackup is not listed among the supported options in https://www.postgresql.org/docs/18/upgrading.html So, pls. let me propose two things: - to clarify how pg_basebackup works with servers of the same or older major version - to clearly specify pg_basebackup cannot be used for PostgreSQL major version upgrade It could be done on the same page https://www.postgresql.org/docs/18/app-pgbasebackup.html Thanks ! best regards Alexey Shishkin
