The current thought is to add some sort of hook that allows a
user-defined action to be taken at the point where a WAL file would
normally get recycled. Presumably this action would involve copying the
WAL file to someplace else (eg a tape), after which it could get
recycled. If you've got any thoughts on exactly how to manage this,
let's take up a discussion on pgsql-hackers.

People are thinking about it, but I'm not seeing a lot of work getting
done. (Partly my fault, since this is one of the things I'm supposed to
be working on...)
