To make my database fast, I often have to do a vacuum full on some key tables. Which is basically a freeze all access to the table, and copy byte by byte to a new physical file. So as your data size doubles, the vacuum full time doubles. Have a table that is so big I basically can't vacuum full it anymore (in an acceptable amount of downtime).
