I'm seeing a similar slowdown, but on much smaller tables (roughly
10,000 and 30,000 rows apiece).  It takes up to a minute to analyze the
10,000 row table (see other messages to this list about the constantly
updating nature of the application using this database).  The weird
thing is that these vacuums took barely any time before a recent
required restart of the database.  Nothing's changed in the config, yet
now the vacuums take a while now.  I'm not sure what to make of it.
The system doesn't appear to be under any sort of increased burden (in
fact, postgres is using barely any resources during the analyze).

As Austin Powers would say, "That's not right ..."
