Aaron,

If I understand correctly what you would like to see from the postgis db is
the tabular data in a mouseover.?
We currently have a perl routine you can incorporate in a 'use' statement in
a perlmapscript app. It is fed arrays for the min/max x & y's for each point
that is to become a mouseover point and queries a db using the perl dbi to
extract the tabular data and create the imagemap area's and the div's for
the show/hide javascript.
If it would help, I can send it to you off-list (just to keep the attachment
from going to everybody).
A sample of the results are here:
