Nathan,
I was involved in the same sort of decision about 9 months ago.
Often these decisions are made by one's IT department as spatial data mangement

ST_Collect worked for me.
I have a column of multipolygons. I can take the ST_Centroid of each
multipolygon and it produces a multipoint.
Don't have the SQL at hand, but it's something close to:
UPDATE table SET geom_multip=(SELECT
ST_Collect(ST_Centroid(geom_multipoly)) FROM table2 WHERE

It's Solaris 10 8/07, the box is only about a year old.
I do get two types of test failures though...
1. I get differences in error message formats.
The tests expect an error message, "ERROR: parse error - invalid
geometry" but the tests return "ERROR: parse error - invalid geometry

Hello,
I was involved in the same sort of decision about 9 months ago.
Generally what we found was that Oracle Spatial supported a basic set
of functions so they can check that features box in sales brochures
saying "yes, we do geospatial stuff", but you have to do it Oracle's
way.
OTOH, PostGIS
This is fixed in PostGIS 1.4.1 I believe -- due out shortly.

Use ST_Multi(point) to get what you want.
You can build your query using ST_DWithin(geomA, geomB, dist).
