relcache reference leak with pglogical replication to insert-only partitioned table?
I understand it's not fully supported to replicate to a differently
partitioned setup on a subscriber with either pglogical or the native
logical replication, however I also know that INSERT triggers can be fired
in replication mode. I have an insert-only OLTP table that I want
partitioned only on the subscriber system. I have this setup using the
"old style" partitioning as it is a 9.6 system.
Provider is 9.6.6 pglogical 2.1.1
Subscriber is 9.6.10 pglogical 2.1.1
Everything appears good as far as the data. It is partitioning correctly.
Queries on the data are planning correctly. However, I am now getting
these WARNING messages constantly. How concerned should I be? Is there a
fix for this? Any insight is much appreciated!

Logical replication has been added to core in v10, and pglogical is
quite a different thing. It may be better to contact the folks in
charge of it here:

It won't corrupt anything but you can expect resource leaks.
I think there are changes to support this in pglogical3. I don't have any
new information on when they might become public, but I do know work has
been done to add a plugin mechanism etc as part of work toward opening
pglogical3.
