Hello, We are running a single PG 9.4 database node we are switching to PG 10.4 (which will run as master + setup of a slave)
To minimize downtime when switching from the 9.4 server to the 10.4 one, I would like to setup a replication stream instead of stopping the production, dumping 9.4 and restoring in 10.4 which my take a lot of time. The next steps would be to reinstall the 9.4 server from scratch with 10.4 and setup this host as a slave, ready to take the master role if needed (hot standby). Can such a replication be established between 9.4 and 10.4 and what replication tool/schema to use ? I have been through the documentation on replication in 9.4 and 10.4 but things are very confusing to me about this point. Thanks for your tips Lionel
