Alter table command is pretty slow - Mailing list pgsql-novice

Hi,

I have installed the PostgreSQL native Windows (8.0 using the Windows
MSI installer) on a Windows 2K box.  I accepted all of the
installation defaults.  It is running successfully  and my application
that stores data via Hibernate 2.0 is working. But it is taking too
long [>15 mimutes] if I try to execute any DDL commands . I Issued
vacuum command just before running a DDL. My computer has 512 MB of
RAM.  Why is it so slow?

Any help would be great.
Thanks in advance
