Three points after a quick test:

- please compile with --enable-cassert, there are wrong assertions in your
code (you might just have to move some lines, there is an Assert() and an
assignment thereafter)

- changing a PGC_POSTMASTER should show a message:
=> parameter \"%s\" cannot be changed after server start;
configuration file change ignored
This seems to not show up anymore with your patch.

- with the same reasoning, I think it's a good idea to display a message
about which option falls back to its default value.
