This is unsurprising: you can only set effective_io_concurrency on
platforms that have posix_fadvise(), which I rather doubt Windows does.

Hm, what I get when I try that on a machine without posix_fadvise()
is
FATAL: parameter "effective_io_concurrency" cannot be changed
I think you have some other configuration problem that's messing up
your log entries.
