I have started looking at the logical replication feature in Postgres
10. One thing I have no been able to determine is the interoperability
between it and pglogical(www.2ndquadrant.com/en/resources/pglogical/). I
know the one is derived from the other, what I can not find is whether a
Postgres 9.4 instance with the pglogical extension installed can
communicate with a Postgres 10 instance using the built in code?

Some testing says the answer is no:

correct

If I am correct, this means from 9.4 <--> 10 and points in between you
would need to use the pglogical extension on both ends.

correct

Going from 10
--> you could use the builtin logical replication. This leads to another
question. Is is possible to use both at the same time?:

9.4       --->   10(instance 1)    ---> 10(instance 2)
pglogical        pglogical
                  builtin                builtin

That is possible.

Thanks for the information.


pglogical will continue to exist, so you can also keep using it if you
already have it.


I tried building the pglogical extension against Postgres 10 and it seems that is not possible yet, which tracks the information on the pglogical page:

https://www.2ndquadrant.com/en/resources/pglogical/pglogical-installation-instructions/

I went to the GitHub repo:

https://github.com/2ndQuadrant/pglogical

and did not see anything that looks ready for Postgres 10.

Am I missing something or is this something for the future?
