How restart of database server influances autovacuum process ?
I think that somewhere on this mailing list I read that autovacuum in such case looses some important information and after database server restart will not behave as expected until VACUUM ANALYZE is executed. Is it true ?

Did you reload (pg_ctl reload) after changing the postgresql.conf settings? Also note that you can alter values for a specific table by putting them in the pg_autovacuum table.
