[HiteshB] I have noted your recommendation and will work with our Product M=
anagement to upgrade to the latest and greatest. Although we can't change t=
he version that the customer has installed (8.2.9-1).

[HiteshB] Point noted. The decision to use VACUUM FULL is something we'll r=
e-examine.
Could you give an example of what an 'extraordinary circumstance' would be?

[HiteshB] We have worked with the customer to exclude the postgre directory=
from their antivirus scans. Hopefully we won't see this Permission issue a=

Thanks again.
