Re: cannot stat `/usr/local/pgsql/data/pg_xlog/00000001000000430000009C': No such file or directory

Ok, I figured out how to get the archiver going again.  This is what I have
in the postgresql.conf file.

archive_command = 'yblogger %p </dev/null'

I temporarily modified the script to not return failure when the source file
does not exist.
I still don't understand why postgres would attempt to archive wal files
that don't exist.  Any wal prior to issuing the pg_resetxlog should be
treated as not needed.

At this point in time postgres had gone away.  I tried to restart Postgres,
but received these messages.  Postgres would not start.

Since this is development I used "pg_resetxlog -f /usr/local/pgsql/data".  I
then tried to start Postgres, but received the same messages as above.  I
removed the backup in progress file as stated in the message.  Postgres was
able to start after that, but now it keeps trying to archive log files that
don't exist.

How can I tell postgres to move to the point in time where log file
truncation occurred where the log files now start?
