I beleive you've asked this a few times already. As a rule it always
best to run the latest minor release, because bugs do get fixed, that's
why there are minor releases.
Do you get this often? Because a reindex fixes it, obviously.

No idea.

I don't think so. I can't imagine why. The client libraries work across
several server versions.

That's for the backend, right? Or not? If it's for the client end you
shouldn't need to change that either.

Do you have a test-case that causes it to happen? That's the only test
there is.

I don't think there's been a bug relating to this. In just about every
case confirmed, it's been memory corruption or disk corruption. As
someone put it:
This [error] says that one of two fields that should never change, in
fixed positions in the first block of a btree index, didn't have the
right values.
No-one has come across an bug that would cause that. Basically, for
more info we need to see the hexdump of the first 8k of the index file
to see why the system thinks it's not a btree. Can you do that?
Have a nice day,
