Ah.

Seems like the log file must have gotten unlinked while still active,
or at least, *something* had an open reference to it.  It's hard to
speculate about the cause for that without more info about how you've got
the logging set up.  (Are you using the log collector?  Are you rotating
logs?)  But I seriously doubt it represents a Postgres bug.  Unlike the
situation with data files, it's very hard to see how PG could be holding
onto a reference to an unused log file.  It only ever writes to one log
file at a time.
