The only way you're going to get out of that is with pg_resetxlog,
which is a fairly blunt instrument :-(. It's possible that you will
have database corruption afterwards. I'd recommend doing a dump and
reload to see if any problems appear. It'd also be a good idea to save
a tarball copy of the $PGDATA file tree beforehand, so at least you can
get back to where you are in case things turn into a complete mess.
Can you tell us anything about how you got into this state?
