Code Issues Releases Activity

Remove support for PostgreSQL 9.0/9.1/9.2.

Browse Source 
Our new policy is to support ten versions of PostgreSQL, the five supported releases and the last five EOL releases. As of PostgreSQL 15, that means 9.0/9.1/9.2 are no longer supported by pgBackRest.

Remove all logic associated with 9.0/9.1/9.2 and update the tests.

Document the new support policy.

Update InfoPg to read/write control versions for the history in backup.info, since we can no longer rely on the mappings being available. In theory this could have been an issue after removing 8.3/8.4 if anybody was using a version that old.
