Nah, just remove them. We've removed, added and changed so many config
options and no-one's ever complained...


I agree with Chris; this would be taking compatibility concerns a bit
far. None of these variables are likely to be touched except through
postgresql.conf (I don't think we even allow them to be SET interactively).
And you can never simply take your old .conf file and plop it down into
a new release.



And the other reason to remove them is that if you don't, you will get all sorts of confusion about people asking, "Which one should I use for pid logging? Looks like both work."



OK, Here's the patch. Also makes some minor improvements in the docco for log_line_prefix.
