So from regression.diff, it appears that in failing in memory
allocation (+ERROR:  invalid memory alloc request size
94119198201896).  My colleague tried to reproduce this in a different
environment but there is no success so far.  One more thing surprises
me is that after
(v15-0011-Provide-new-api-to-get-the-streaming-changes.patch)
actually, it should never go for the streaming path. However, we can
not ignore the fact that some of the changes might impact the
non-streaming path as well.  Is it possible for you to somehow stop or
break the code and send the stack trace?  One idea is by seeing the
log we can see from where the error is raised i.e MemoryContextAlloc
or palloc or some other similar function.  Once we know that we can
convert that error to an assert and find the call stack.
