We could, but I don't see how it could be wrong, as it's only set in
PGSharedMemoryCreate and when we pass it down from postmaster to
backend. If something we're being stomped on there, I'd expect it to
be a more random problem.

<reads code some more>

Although, the reattach does get called almost immediately following
the backend variables being read, so maybe they are getting clobbered,
and it's pretty much always shows up in the re-mapping of the shared
memory.

What distribution are you running? I'll see if I can hack up a build
with the extra debugging, but I need to get the integer_datetimes
option right for your database.
