If you are using MapServer 5.0 or the brand new 5.2 then you can
probably use attribute binding, which allows you to specify an attribute
in your data as the source for various parameters in the map file. For
instance, if you have a field in your database called point_size that
has a size value then you can do this:
SIZE [point_size]
You can also bind to COLOR and most other attributes inside STYLE and
LABEL. I just went to look for documentation on attribute binding and I
can't seem to find anything beyond the original rfc
(http://mapserver.gis.umn.edu/development/rfc/ms-rfc-19) so if you are
running into trouble, don't hesitate to ask the developers :)

Hi all! I'm firing up a mapserver for our company these days. Mapserver
successfully connects to Postgres, and draws points from my database.
But I need to change some parameters, such as colour and size of points
on-the-fly, depending on the duration of their existence. Is there a
way to make Mapserver to pick size and colour of points from Postgres,
too?
