This has been proposed a number of times, but is still infeasable for the
simple reason that a lot of settings are dependant on how much RAM you have
on the machine. "Sample configs" would just result in people trying to set
their shared_buffers to 150% of system RAM if they have a lightweight system,
or in having 500 different sample configurations, which would produce even
*more* user confusion.
A generator makes more sense.
