The one for the referred bugs is: Avoid re-distributing cache invalidation messages from other transactions during logical replication (vignesh C) Our previous round of minor releases included a bug fix to ensure that replication receiver processes would respond to cross-process cache invalidation messages, preventing them from using stale catalog data whi= le performing replication updates. However, the fix unintentionally made th= em also redistribute those messages again, leading to an exponential increase in= the number of invalidation messages, which would often end in a memory alloc= ation failure. Fix by not redistributing received messages. The commit for v16 is b2ae077205e. --=20 Euler Taveira EDB https://www.enterprisedb.com/
