Now you've got my attention ;-) ... this is completely at variance
with my theories about the cause of the problem. Destruction of
a theory is usually a sign of impending advance.

Good. I am dead tired and am about to go to bed, but if you can
reproduce with a debuggable build then I would definitely like to
crawl into it tomorrow.

At this point I do not have the faintest idea what might cause the
problem to go away, so if possible I'd urge you to do the minimum
possible work on the system overnight. Alternatively, if you can
spare the disk space, make a tarball copy of the whole $PGDATA
tree while you have the postmaster shut down. Then we can
study the problem offline without worrying about your live
application.
