Sounds like we have a smoking gun.  Could you show all your non-default
postgresql.conf settings on the master?  I'm wondering about
full_page_writes in particular, but might as well gather all the
relevant data while we're at it.  Easiest way is:

select name,setting from pg_settings where source not in ('default','override');
