Re: Upgrading 9.6.9 to 10.4

Take a look at pglogical ... we've used it for 9.4 -> 9.6 and the same theories apply going to 10.x I imagine. People have used it in combination with pgbouncer to achieve near outage-less upgrades. Some helpful links below:

Hi all,

My employer is in the process of upgrading PostgreSQL, and they would like me to make this happen without any real interruption of service. As I understand it, 9.6 does not support the publish/subscribe model like 10.4 does, but logical replication is the basis of that model. So, does anyone have any suggestions for how to implement the receiver side on a 10.4 server? Or could you at least point me to some sort of how-to page?

TIA,
Jay
