Postgres Port update

Ivan,

	I have fixed most of my problems with a small change.  
Unfortunately, I think it might be a BIG performance pig.  I have added 
code to FS::Record::new to automatically strip trailing spaces off of 
strings read from the the database (if datasrc =~ m/Pg/).  To do this, I 
have to dereference $hashref, and then I match field for a trailing 
space.  If it has a trailing space, I unpack("A255" it.  I was wondering 
if you might have a recommendation of any ways to speed this up.
