The GMap demo has query examples... It's on DMSolutions site.

If you also are doing some other stuff that might justify the use of
PostGIS, go for it, I find it a lot more intuitive for us non-GIS
techies to do the queries:

"SELECT attrs FROM spatial_table WHERE <WKT string of the point or box
the query is being made> && <geom_col> AND truly_inside(<geom_col>,<WKT>)";

And because every table is a layer (well, not necessarily, but is
probably the most common case) the multiple/single query issue is trivial to
solve. Also you can do joins/subselects etc, and bring data from other
sources that are not present on the spatial table.
