'I want to set the Streaming replication between two different postgresql versions
my primary server is Postgresql-9.4 and the secondary server is Postgresql-13, I followed all the steps but while restarting the secondary server, I am facing the error "An old version of the database format was found. You need to dump and reload before using PostgreSQL 13." how I should resolve it.
Solution 1:[1]
You cannot have streaming replication between different PostgreSQL versions, and you cannot have logical replication with versions less than v10.
You will have to use trigger-based replication like with Slony-I.
