[SQLObject] How to use OVERLAPS keyword with SQLObject?

[Matthew W. <ma...@tp...>]

I just learned about the OVERLAPS keyword, used like this:

matt=# select (TIMESTAMP '2008-07-24 03:00:00', TIMESTAMP '2008-07-24
09:00:00') overlaps (TIMESTAMP '2008-07-24 5:0:0', TIMESTAMP '2008-07-24
11:0:0')
;
 overlaps 
----------
 t
(1 row)


I'm testing if the time interval from 3 AM today through 9 AM today
overlaps the time interval from 5 AM through 11 AM.

How can I use this with SQLObject?

I poked around a little with SQLOp.  Before I write an ugly patch, is
there already a way to do it?

It is important to use the TIMESTAMP label to disambiguate types.
