To install this package:

 -- make sure you have the correct version of ActivePerl (5.8.0.805)
 -- make sure you have DBI.pm already installed

 -- decompress this zip file to a temp directory
 -- from that directory, run 'ppm' (you might need to add it to your $PATH)
 -- in the ppm shell, add a local repository for the current directory if one is not already there
 -- type "install DBD-Pg"

 -- after installation, you can safely delete the decompressed files in the temp directory
