Thanks.  I find it strange that it takes 3 minutes to restore a 150 MB
database ... do you have many indexes?

Even though the restore times are very similar, I find it a bit
disturbing that the "CREATE INDEX" is shown to be waiting.  Was it just
bad luck that the ps output shows it that way, or does it really wait
for long?
