Old pg_clog files

[Ron Johnson <ron.l.johnson@xxxxxxx>]

Hi,

v8.4.17

http://www.postgresql-archive.org/pg-clog-questions-td2080911.html

According to this old thread,  doing a VACUUM on every table in the postgres, template1 and TAPd databases should remove old pg_clog files.

postgres=# SELECT datname, age(datfrozenxid) FROM pg_database;

  datname  |    age   

-----------+-----------

template1 |   9951058

template0 |   9814761

postgres  | 163406258

TAPd      | 179543997

(4 rows)

However, while about 40 of them have been deleted, 183 still exist.  What did I do wrong?

Thanks
