I think the reason for the instability of the test in 14 and 15 is
that we don't have a predictable way to start streaming in those
branches. We rely on the size of the reorder buffer. This can vary
based on some background activity autoanalyze or others which can
generate WAL records. So, will think some more on it tomorrow on how
to make it reliable in those two branches. For other branches, we used
GUC debug_logical_replication_streaming to control the streaming
behavior.
