Thank you for your answer. I'm sorry I really didn't explained well my problem :/
For example if I have a table test like this : CREATE TABLE test (min real not null, max real not null, desc character varying not null); and I want a constraint exclusion to make sure the range min/max doens't overlap I can't write ALTER TABLE test add constraint test_exclude EXCLUDE USING btree ((min,max) WITH &&) I saw the extension temporal gives a new type PERIOD and has operators like &&, but only for timestamp, so I'm wondering if I must code something something similar or if there's is an easier way On Wed, Oct 12, 2011 at 11:23 PM, Simon Riggs <si...@2ndquadrant.com> wrote: > On Wed, Oct 12, 2011 at 10:16 AM, Julien Rouhaud <rjuju...@gmail.com> > wrote: > > Hi everyone, > > Is there an easy way (that I maybe missed) to use constraint exclusion > with > > 2 floats ? > > Must I find an extension the temporal extension which create a new type > with > > 2 timestamp or can I usethe && operator with 2 fields ? > > There's nothing in constraint exclusion that depends upon specific > datatypes. > > Let us know if you find a problem with floats. > > -- > Simon Riggs http://www.2ndQuadrant.com/ > PostgreSQL Development, 24x7 Support, Training & Services >
