Downgrading a package, using apt-get

["Sam Minnee" <sam@totallydigital.co.nz>]

Hi all,

 

I am needing to install postgresql 7.1.3, in order to convert an old data set (the raw data files, not the dump).  However, postgresql 7.3.2 is currently on my machine. 

 

 * Is it possible to use apt-get to downgrade a package?

 * Is there another better way of installing an old package?

 

Thanks,

Sam
