Hi,

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

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

Reading the old thread it sounds like it might require multiple vacuums to affect complete removal.

I vacuumed them twice.

Does it matter whether I ran a VACUUM ANALYZE on every table instead of "vacuumdb --all"?
