That makes alter system set a bunch less useful, but might be
insurmountable.
Anyway, I also regard this as a problem we need to resolve now that we
have the config directory if we expect people to build autotuning tools.Once someone is relying on an autotuning tool
whichdrops a file in
config/, it becomes a real problem that there are uncommented
PGC_POSTMASTER options in the default postgresql.conf.
I'm not sure what the solution to that problem should be, but I do know
that we're going to hear it a lot from users as includes and the config
directory get more common. Certainly any solution which says "first,
manually edit postgresql.conf" makes the config directory into a kind of
joke.
