I find the pglogical package has updated, I reinstall the new RPM package and test again. But I find the same error in subscription node after I run pglogical.create_subscription command:
Please don't side-track threads about patch review and development with requests for support of a released version.
This thread is about getting pglogical into PostgreSQL 9.6 core, rather than the separately released product that's been released to support 9.4 and 9.5.
