I'm running a PostgreSQL 8.4.12 with a single database which has over the years grown in size. I remember recently seeing the database size in phpPgAdmin being about 250MB but today I noticed that this has gone down to 154MB. Just wondering if it is normal for a database size to all of a sudden become smaller?
