Yeah, I was wondering if its checkpoint delaying logic might have
got the checkpointer jammed or something like that, but I don't
currently see how. Yeah, the replay of bulk newpages could be
relevant, but it's not exactly new technology. One thing I wondered
about is whether the Perl "wait for catchup" thing, which generates
large volumes of useless log, could be somehow changed to actually
show the progress after some time. Something like "I'm still waiting
for this replica to reach LSN X, but it has so far only reported LSN
Y, and here's a dump of the WAL around there"?

Hmm.
