??? "vacuum" is an sqlite command; it is PostgreSQL like syntax
equivalent to what most databases call "UPDATE STATISTICS" [although it
does have a somewhat different connotation].

Many applications use SQLite and suffer from this same problem.  I wrote
a script that searched for SQLite database and vacuums them all.

Applications have gotten better about the care and feeding of their pet
databases, but running through them occasionally doesn't hurt - and
sometimes releases a surprising amount of disk space.
