I have started looking at the logical replication feature in Postgres

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?
