Could not open file "pg_clog/0000": No such file or directory

I am getting the error like following while accessing a Postgres database

ERROR:  could not access status of transaction 69675
DETAIL:  Could not open file "pg_clog/0000": No such file or directory.

I didn't do anything with the pg_clog folder but the 0000 file is not there. Is there any way to recover that file or in any way to fix this issue? Any help would be appreciated.

You are experiencing database corruption, and you should restore from a backup. You should try to figure out what happened to the database so you can prevent it in the future.

• Is your storage reliable?
• Are you using dangerous settings like fsync = off?
• Were there any crashes recently?
• Are you really running 9.1? If yes, you shouldn't do that, as it is out of support.
• Are there any files in the pg_clog directory? There should be.
• Did you have an out-of-space problem recently that may have led someone to remove files from a “log” directory?
