It seems confusing if we rename the tool but not the documentation file
name. Let's put a blinking message in the release notes saying 'tool X
was renamed to tool Y'. The only thing we should do is add on each tool
page something like: pg_waldump (formerly called pg_xlogdump) ...

+1. If the packager wants to do those aliases, it is up to him/her.

In those cases, let's keep the functions as wrappers and undocumented.
In a few releases, we could remove them without breaking softwares that
rely on them.
