Dear Hayato,

Thank you for the review! My apologies for the error in the patch -- it
looks like I accidentally modified it before sending =(. I've attached the
fixed versions below.

I just found it easier to restore the original state of
'postgresql.auto.conf', as removing parameters from the file resets them to
their default values. This approach achieves the same final state without
having to explicitly set each one.
