Hello,

is it supported to restore binary backup (pg_basebackup) taken on an amd64
platform on arm64 while using the same PostgreSQL version?

I'd like to know, whether there is binary file compatibility to save time
needed for dump & restore migration scenario or all the complexity of using
logical replication to migrate databases already utilizing logical
replication.

Kind regards Ales Zeleny
