Illegal log output is like disk crash - only BAR can help.
I agree that elog(STOP) caused by problems with single
data file is quite annoying, it would be great if we could
mark table/index as corrupted after recovery, but there are
no means for this now. For the moment we can only notify
DBA about problems with file node and ignore further
recovery of corresponding table/index - I'll do this
for beta2/3 if no one else.

You would get totally corrupted database. Remember -
WAL avoids not only fsync() but write() too.
