Hi,

What would be the best representation of the point type?

So far, I have been using following for query:

(:[] 'point-column 0)
(:[] 'point-column 1)

and this for update:

'point-column (:type (concatenate 'string
			 (write-to-string x-coordinate)
			 ","
			 (write-to-string y-coordinate)) point)

It works, but seems a bit of a kludge.

And how about more complex data types that use points like these
http://www.postgresql.org/docs/8.4/static/datatype-geometric.html ?
