Status of cluster file encryption

Here is a status report of where I think we are with cluster file
encryption.

The last patch for temporary file I/O centralization is from April 20:

https://www.postgresql.org/message-id/24759.1650466826@antos

Once that is done I can modify my patch set to switch from CTR to XTS
mode and hook into the temporary file I/O centralization code. After
that, we need to work on the WAL encryption code and tool support.
Replication must also be handled.

I think once the temporary file I/O centralization is done we can
consider putting some of my patch set into the tree once PG 16 opens for
development --- the first step might be the key management feature.

I have updated my cluster file encryption presentation to show diagrams
of the architecture:

Hopefully that helps.
