Hi, This change seems to have introduced an issue where a deleted context can be restored. This happens when a replication command exports a snapshot since the transaction used is aborted at the start of the next command. This leads to a memory context allocated with itself as a parent and child, triggering an infinite loop when attempting to delete it. I've written more details in a separate thread[1].
