Hi,
Do you mean the original bug: "pg_get_publication_tables function will output
duplicate partition relid when adding both child and parent table to the
publication(pubviaroot = false). " ?
We decided to commit the fix for it only in HEAD as there is no user complaint
about this and it might not stop any user's service unless it relies on this
view's output for the initial table synchronization.
Or do you mean another one mentioned here which is "the changes on newly
attached partition won't be replicated" ? For this one, I think it's fine to
backpatch the fix and I can prepare the patch for back branches if needed. BTW,
if we want to backpatch this fix we might need to keep the order of
RelationSyncEntry struct member unchanged in back branches.
Best regards,
Hou zj
