I had a similar problem.  I decided one day to "clean" out
The pg_clog/ directory of the database cluster.  These files'
"last modified time Stamps" on many files were quite 
old, so I deleted them.  This didn't have any consequences for
the data (dumps or indexes etc.) or the operation of 
the installation except, as I found out MUCH later found out
- I could no longer vacuum the Database.

I restored the missing files from a backup and everything
was okay again, after a vacuum of the database the
system cleaned out the older pg_log/ files on its own.

I hope you get things fixed!

My best regards,

Stefan Becker
