I have been playing with this file and DIA-0.96.1 on Linux and this is
the result:

* Importing/converting from xfig to dia format worked with almost no
problems.

* DIA complained that it could not find 'Latex font 16' and that it
would use 'sans' instead. An explanation about this could be what they
explain in this url: http://projects.gnome.org/dia/fonts.html

* The diagram was imported automatically with the right layout but
without the red color in the boxes. This was fixed without problems
manually.

After converting this file to DIA I have generated several other formats
from it. Here are they: http://folk.uio.no/rafael/pgsql_diagrams/

* png, jpeg and eps are generated with the right layout, color and font
size.

* xfig is generated with the right layout and color but the font size is
too big

* svg has big problems with the font size under google chrome and is
'almost' right under firefox.
