Thanks for the review!

I've fixed the typo and attached an updated patch. I also incorporated
Chao's comments from upthread. I'm planning to commit this to master.

As for backpatching, I'm hesitant to backpatch the full patch since it may
reduce the number of replication feedback messages, which feels too invasiv=
e
for stable branches.

That said, the patch's changes in walsender.c could be backpatched.
As discussed earlier, they don't fully address the reported issue,
but they do help mitigate cases where lag becomes NULL unexpectedly
in logical replication. So it might be worth considering those changes
for stable branches.

Thoughts?
