Family operator strategies

Operator overload	Strategy	Purpose	Membership scope	Source description
<(interval,interval)	1	search	Family member	less than
<=(interval,interval)	2	search	Family member	less than or equal
=(interval,interval)	3	search	Family member	equal
>=(interval,interval)	4	search	Family member	greater than or equal
>(interval,interval)	5	search	Family member	greater than

Family support functions

Support number	Left type	Right type	Function signature	Result type
1	interval	interval	interval_cmp(interval,interval)	int4
3	interval	interval	in_range(interval,interval,interval,bool,bool)	bool
