That's correct - initdb doesn't work when you've built on WSL as
*somehow* HAVE_FDATASYNC is set to 1 by configure - but it ends up not
being included by #ifdef blocks. This causes the following PANIC

PANIC: unrecognized wal_sync_method: 1

Which happens because wal_sync is set to 1, but in
src/backend/access/transam/xlog.c that block in the switch is inside the
#ifdef so never gets checked,
