Log Message:
-----------
Rewrite docs for new libpq keepalive parameters.
The revised documentation makes it more clear that these are client-side
parameters, rather than server side parameters. It also puts the main
point of each parameter first, and consolidates the conditions under which
it might be ignored in a single list at the end.
