I need to vacuum full the database but got this error
mydb=# vacuum full;
ERROR: could not access status of transaction 376865319
DETAIL: Could not open file "pg_clog/0167": No such file or directory.
Solution per searching google.
-bash-3.2$ dd if=/dev/zero of=/pgsql/data/pg_clog/0167 bs=256k count=1
Then VACCUM FULL again.
