Well, that depends on what you think the typical-case complexity is
and on how long a line will fit in your editor window ;-).

I think that we can't make much progress on this argument without a pretty
concrete idea of what typical and worst-case configurations would look
like.  Would someone like to put forward examples?  Then we could try them
in any specific syntax that's suggested and see how verbose it gets.

FWIW, I tend to agree that if we think common cases can be held to,
say, a hundred or two hundred characters, that we're best off avoiding
the challenges of dealing with multi-line postgresql.conf entries.
And I'm really not much in favor of a separate file; if we go that way
then we're going to have to reinvent a huge amount of infrastructure
that already exists for GUCs.
