My first thought would be to create a VIEW in Postgres, joining your spatial
information with the secondary information that you want to use for styling.
Rather than configuring your actual spatial table in GeoServer, you would
set GeoServer up to serve tiles from the view, which would automatically
reflect updates to the styling information.
It's fairly simple from there to create an SLD which determines styling
details based on feature attributes, and all map viewers would see updates
immediately (apart from browser caching.) There are some basic examples of
such data-driven styles in the "SLD Cookbook" section of the user manual.
The suggestion of regenerating SLDs when data changes is also a good one,
especially if you don't want to run a postgres server. If you are using the
GeoWebCache service embedded in GeoServer then your cache will automatically
be invalidated when the style is updated, so you would be able to use cached
tiles with minimal upkeep.
