Thanks: I found a cache of the article, which is entitled,
"Q10087 - INFO: Is PostgreSQL remembering what you vacuumed?"
http://72.14.253.104/search?q=cache:n_LQiTbm9joJ:www.pervasivepostgres.com/instantkb13/article.aspx%3Fid%3D10087+%22Is+PostgreSQL+remembering+what+you+vacuumed%3F%22&hl=en&ct=clnk&cd=2&gl=au
A simplistic summary is to do a full, verbose vacuum of the entire
postgresql installation (of all the databases together), and then the
last two lines contain output about FSM utilisation.
The values of max_fsm_relations and max_fsm_pages should then be set
in postgresql.conf in light of this information.
