Re: WAL archiving is stuck on an old file that was deleted -- how to get it going again? (8.4.2)

Bad, bad idea. Get rid of that. Perfect way to corrupt your system.
Postgres removes pg_xlog files automatically when they are no longer
necessary. If it doesn't remove them, something is happening and you
need to fix *that*. Deleting files by hand only works around the
wasted-disk-space symptom in a bad way.

I suggest you get some monitoring in place to prevent this from being a
problem in the future.

You're screwed. You need to get a new base backup; all the files
you have archived previous to 00000001000000350000006E are useless.

You can get out of the problem by creating a dummy file with that name
in pg_xlog, but keep in mind that the archive is now completely useless
and unrecoverable.

Sorry.
