OK, I have done this refactoring effort as attached because I think
that's really worth it. And here are the diff numbers:
3 files changed, 113 insertions(+), 162 deletions(-)

singularities of bytea in its output and the way TIMELINE_HISTORY
takes advantage of the message level routines. Still for
gains in readability are here.

What do you think?
